Should I break up or detach after testing him with a fake account?

I’ve been seeing this guy now for 3 months and we have a really good time together he texts and calls me all the time wants to spend time with me. Before we started seeing eachother he was in a relationship like a month before we started going out so that start didn’t help with me trusting him. I wanted to test him so I texted him on a fake account a few weeks ago and he replied saying that he’s flattered but he’s seeing someone and doesn’t wanna be disrespectful to that person. So I unfollowed him on the account thinking it was over and today like 2 weeks later he re requested the account. This really bothered me and now I don’t know if I should send another text or leave it the way it is because him looking her up and re requesting her says a lot already. Since it happened today I’m not sure what to do or where to go from here. I’m trying to detach and be realistic because I was falling for him and was building trust but this just completely destroyed it. Im just wondering if he followed her again because he isn’t interested in me as much as he says and acts like he is or if he wants to keep his options open or whatever other reason it could have been for. If I were to end with him I’d say that I really like him a lot but I cannot manage being in a relationship and being in school full time because I am a full time student. I tested him in hopes it would ease my trust issues but it made it worse and i genuinely don’t know where to go from here because I do like him. Please give me good solid advice and don’t be really mean because I’m struggling I feel like sometimes I’m the issue because I’m 22 and and I’ve never been in a long term relationship and I really want that for myself. Before him I wasn’t seeing anyone for 2 years and I don’t wanna have a desperate mentally but it takes a lot for me to like a guy and I like him and I don’t wanna have to wait another 2 years to find someone else that I like
