I miss my ex so much and I regret breaking up with him so bad. It's been months for him but I've been in a bad place and only let myself process the emotions over the past weeks. I try to get on with my daily life but I keep coming back to wanting him back, to the point I'm getting sick. When we broke up I hurt him really bad and I will forever be guilty and want to amend it, but last week when I finally asked him to get back together he said he can't, and I feel like I've made the worst mistake of my life. I told him I'll still leave the door open for him if he ever wants to come back, he said there's no way I can and he looked so in pain. I'm with someone else now who's good to and for me, but it's not the same. As much as I want to, I can't love him the same way he loves me. Maybe I did, but now all I can think about is my ex and it's not fair on him. I'm afraid I'll have to hurt him too. I hate this and I hate myself for putting me in this position.
