Been crying over guy (22M) that left me (20F) for ex

I was going through it over typical college student/life stuff so I decided to go on a dating app to distract myself. I met up with a guy and after talking for about 30 minutes we went back to my place. That was the first time I had ever gotten intimate with someone I was not in a relationship with. I lost my virginity to him. I was fully expecting it to be a one night stand but when we were cuddling after he started saying that he doesn’t want to sleep with anyone else, this is the closest he’ll ever be to me, and that he wants to see me again. I liked how it was emotional for him and so I didn’t want him to leave and he didn’t until hours later (we were talking and going in and out of sleep).

He came back the next day and we didn’t really do anything intimate. Just talked. But my biggest regret is how awkward I was. I don’t really know how to socialize so I was pretty closed off and quiet and I’m afraid that I bored him. He texted me after saying he had a nice time. His texts were affectionate and we had plans to meet the following week, I was content. But I had suspicions something was up when it had been almost two days with no response. I texted him and his response was nice but he said he was unsure if we could see each other like we wanted. The next day when I was supposed to see him he told me he was sorry, but ”someone came back into [his] life” and that it was nice meeting me with a heart emoji.

It took me like ten second to process that before I started crying. He took my virginity, and once I found out he liked me, I was looking forward to whatever came next and got so attached. But I thought it would last more than 7 days :( I responded to his text by asking him if he was telling the truth or if he just lost interest in me. I also said that whatever the reason is I understand, and I didn’t want to make things harder for him by bothering him with texts. I said he could text me in the future if he changes his mind. He never responded and it’s been four days. I’ve just been crying and lying in bed these past four days, occasionally getting up to do an assignment and maybe eat.

I can go on about the things I like about him. He’s different than the other guys I’ve dated. I think he’s special and I don’t want to let go of him. Of course I will not beg for a response when he likely has a lot on his mind with an ex coming back. That will only push him away. All he mentioned about his past was that he and his ex broke up a year ago and he had recently deleted all photos of her. I don’t know if that ex is the same “someone” that is back but based on some old comments I found on his social media he’s been hung up over her as late as December. What I tell myself to feel better is that his ex must’ve found out he was on a dating app and reached out—not because she loves him—but to not feel replaced. Like an ego thing. But what do I know :/

I want to wait 2 months or something before I reach out to him. Should I even do that? I do not want this to be the end :(
