split up with bf for uni now hes found someone else and im hurting Watch
Sounds like you didn't care enough about the relationship at the time to want to/try to make it work when you started uni and now you're disappointed your backup option isn't actually an available backup. It doesn't matter if they last or not, what gives you the right to try and break them up after he told you he is only open to friendship and really likes this person? An hour away is not the end of the world, and breaking up with him because you didn't want to be "tied down" shows your feelings towards him and the relationship. Sounds like grass is greener syndrome, but having explored new pastures you've decided the patch you had wasn't all that bad.
Let him go, move on. Probably you're just a bit lonely at the minute which is confusing your feelings. You wanted to end the relationship for a reason, that has consequences. I'm sure when you ended it you thought the positive consequences outweighed the negative ones.
Aside from that, it's normal for lots of people to feel homesick in the first few weeks of starting uni. Explore your interests, try and make new friends, new experiences, and do whatever it was you wanted to do that you felt a relationship would have held you back from. It will help you move on and feel less homesick.
I broke up with my bf at the end of A levels because I was going to uni and he planned to go into work I felt there was no point being tied down as I was going to uni an hour away, anyway I the first few days I got chatting to people but I feel very homesick and now wondering if im making mistake going to uni. I messaged my ex saying can we meet up soon and maybe try again but I got a message back saying he has found someone else and says we can only be friends as he really likes this new girl. I sat and cried all night I felt so alone I feel so stupid now for ending it with him. Will they last? should I plead and tell him I will never let him down again?
He has found someone who seemingly is better for him and makes him happy, and there's nothing you can do. What did you expect him to do - wait for you to change your mind? I'm sorry if it sounds harsh, but this is the reality now.
You need to let him go and move on. Don't go begging to him as that won't make you look good.
