Caught my boyfriend cheating on me with other guys

I (20F) and my boyfriend (21M) have been together for over a year. My boyfriend and I just moved into our own apartment about a week and a half ago.

Backstory: My boyfriend and I have known each other since I was 14. We have always been friends and nothing more up until a year ago. In his past relationship he was cheated on physically, but that was when he was 16. He always tells me he now has trust issues because of it. He preaches loyalty, trust, and communication is key in a relationship. He has always been somewhat jealous because of his past which is understandable. I often times have to tell him that I have never given him a reason not to trust me and that I will always be solely loyal to him.

About 4 days ago, he was sleeping and I will occasionally go on his “boys only” group chat on snapchat and type something funny in the chat. Everyone in this group chat we know IRL. I went to swipe out of snapchat and saw Reddit in his background apps. I have personally never seen him use Reddit nor did I know he had an account. Me being curious, I looked through it. His account seemed pretty empty ( I also don’t use reddit that much so I also didn’t know what to look for). But i did find that he commented a “❤️” under a dick pic from a transgender woman. This comment was made the day we moved into our apartment. At first I thought this was weird. He doesn’t seem like the type of person that would be gay or bisexual. We will sometimes make gay jokes in our friend group and he laughs at them and makes them back. He HATES when I touch his butt and gets mad at me when I do lol. So presumably when I saw this comment I was a little confused.

I told my mom about this and she told me I should wait and see if anything else comes of it. As it was only a comment and I generally don’t care if he watches porn. If this was something he was into I was open minded into accepting it. I did want to dig deeper on this and find out more information and trying to understand whether this was an accidental comment or if there was more going on.

Today, he was sleeping around mid day. His phone was on the floor on my side of the bed. I picked it up and looked through Reddit again. I checked to see if the account was under his email or phone number, which it was. I checked through the messages and found 3 DM’s from men. He was asking for videos of men masturbating and was asking for snapchat info saying he would send pictures on there. I felt my heart drop. I could feel myself shaking, getting a lump in my throat, and my blood physically boiling. I immediately took out my phone and started taking pictures for evidence. I called my mom shortly after and sent her the pictures I took. She helped me get my thoughts straight before confronting him.

I woke him up out of a dead sleep holding his phone. I told him he needed to get up and we needed to talk. He obviously looked scared and confused. I asked him who he had been texting. Of course, he hit me with the “what are you talking about?” I told him that I saw he has been messaging people asking for nudes and has been sending nudes. For a second he completely denied it, scrambling through his phone like he was lost and had no clue what was going on. I said “So you haven’t been messaging people on Reddit?” At that point, he knew he had been caught. He admitted to what he did. I then mentioned that it was other gay men and transgender women. He immediately said “What are you taking about?” Again. Quickly after he said “You know what, I’m not even going to act like I don’t know what you’re talking about.” He started to cry and I told him he shouldn’t be the one crying right now. I asked him if he was bisexual. Even if he is I am totally okay with, as I have experimented with women myself in the past. He said no. He profusely apologized and said that he made a dumb mistake. He then tried to ask why I went through his phone. I told him that is not the point. If the roles were reversed, that would be the last thing he would be worried about. I kept pressing for an answer why. He told me a couple months ago he was curious and started watching transgender porn which then led to gay porn. Like i said, if that’s what he’s into, cool. But I was very upset that he was seeking out attention from other men and messaging them, sending and receiving nudes. I told him how humiliated, insecure, and disrespected I felt. I told him that he preaches loyalty and that he has trust issues with cheating and then he goes and does this. I was very calm and firm with him. I didn’t yell, didn’t shut down ( which is my go-to when I’m upset). Didn’t even stutter once when i told him how wrong he was for doing this to me. I told him he needed someone to come pick him up and for him to leave because i couldn’t even stand to look at him. He had his dad pick him up and they drove around for 2-3 hours.

When he arrived back, he sat in the living room. I walked in and asked what him and his dad talked about. He told me he told his dad everything, including the messages being sent to another man. He also told his mom as well. They are both on my side. Both of them are very angry and upset with him as I have done so much for him. I continued to ask why he did it and when he found the time to do it. I work overnight shifts and typically sleep during the day and work from 8p-8a, 3 days a week. He told me that when he got horny and either i wasn’t home, sleeping, or didn’t want to have sex he would message these men. I asked if there was something wrong with me, and if there was something i couldn’t do for him that he wanted sexually. He said no, that it was nothing wrong with me. He told me that he wants to try and make things right. He said he would do anything to keep me from leaving him. He told me I could delete any and every app from his phone if I wanted to. I told him I shouldn’t feel like I need to restrict him. I said It’s not about controlling his apps, it’s about him choosing respect when no one’s watching. He still continues to apologize. I told him that I still love him, and even though he betrayed me it doesn’t mean my love just automatically shuts off. But it will definitely take time to see if we could even work.

How else should I go about this? Any advice? Anything else I should mention to him? TIA.
