I feel like my (F) soon to be ex boyfriend (M) was a stranger

Hi all,

Just wanted to come on here to type out all that has been happening over the last couple of months.

So I’ve been dating my boyfriend for a year and a half now. He was my first boyfriend and I was convinced we were on the same page about so many things, and could definitely end up together forever.
A couple of months ago I found out he texted an onlyfans model online, sent her a nude as well. I was shocked, and wanted to break up with him. He convinced me to stay, that it would never happen again. I didn’t trust him after that though, and slowly, after I started going through his phone, I found out more, even worse information. Firstly, he and I were pretty clear about being honest about our past, who we’ve been with. Well, he’s lied about that. I found out he had sex with a girl, has had previous relationships and more.

Here’s where it gets even worse.
A couple of weeks after this, I found an account on one of his social media pages. Here, he follows over a 100 transgender accounts, which is odd since he’s been very clear about not understanding the community and not feeling comfortable with lgbtq+. I confronted him and he tried to give me this lame excuse that unfortunately at the time, I believed. All I wanted was some honesty, instead of asking him multiple times if he’s interested in anything other than cis women. He got defensive and shut the conversation down pretty much immediately, which I maybe should’ve taken as a sign..

Now, today. I went through his phone. He’s been talking to girls on Snapchat with them sending nudes, lots of them. He is careful enough to delete these girls before we are together. I also found out he bought many s** toys, some before we were together, some during. Anal toys..which we don’t use. I found out he uses them on himself, to humiliate himself. He also downloaded tinder, hinge and yubo in the last week. He’s messaged men, transgender people, girls, pretty much everyone. Usually just a short conversation, nothing more.
I went on another app and saw another conversation with a boy, who invited him to come over since he was home alone. He wanted to see him again. Which means they’ve seen eachother before, and maybe hooked up. I don’t know if they used protection.
I will be getting tested, and hope I’m okay.
I’m 21, I never thought my first relationship would unfold to these horrific findings. I was supposed to move in with him in a month. I could stay at home, but it’s small and I don’t want to inconvenience my family.
Obviously I will be breaking up with him. I know I will get over it, but I just wish I never met him. I already know I’m going to be left with trust issues.

He’s still asleep next to me right now. I’m planning on packing the stuff I can right now, and then leaving. I’m scared of confronting him, he’s very much in the closet and I don’t know what will happen when he finds out I know everything.

Thank you for reading and I will try to keep you updated if necessary.
