The summary of my life so far:

(Ramble-y sorry)

Currently 20. Almost 21

Had my first boyfriend ages 18-20

Broke up due to familial reasons

Felt guilt for not being a good girlfriend, still do. He, however, thinks I'm the best thing to have ever happened to him and he is upset over never finding someone better

He's a lot less social than I am. He has the capabilities for sure, but he's introverted and prefers to be alone. However, he would be lonely if I wasn't around. We see each other 5 days a week. When we were dating we saw each other every day. It hurt me a lot when I had to negotiate having the weekends to myself after we broke up

He moved to my city away from his family (despite me telling him NOT to move here for me). He's here for another year

I now have a crush on someone else (30m), but I can't be with them anyway until the professional relationship changes. I have a feeling he likes me too, but

I want to stay close friends with my ex because I don't want him to feel upset or lonely. I also, admittedly, want to make up for all my wrongs. So I'm thinking of postponing relationships for his sake

But I also feel bad over this lost opportunity... My crush knows I like him, and he wants to discuss it after the professional relationship is gone. He also knows about my situation with my ex.

I don't know. It's a mess. My emotions are always high about this whenever I have a good time conversating with the crush. But the thing is... when i thought about potentially having to tell my ex that Ive found someone else, i actually had a mini-panic

Also if this is relevant info: I'm not into casual sex, and I get really attached to people. I also feel like I'd be a horrible person if I reject the crush. It's like a no-win situation for me. I'm a people's pleaser (i suppose) and I have a hard time saying no to things. I can see myself agreeing to something casual if he asked for it. Not because im crazily into the idea but because i feel like id be horrible by staying just friends with him in that case

What should I do? Im considering just being close with my ex whilst focusing on my studies. Hed be moving away in a year's time and we do plan on mostly cutting ties by then
