Where do I stand? What do I do now?

My ex and I used to be so happy before, but there was this huge problem that stuck with us and made us become distant. It grew and we decided to break up because we needed to figure out who we wanted to be before being together. At first it was hard for me because I wasn't used to it, but as time went by, I began to live with it and finally stopped depending on him. I became independent, and I loved myself more. My ex, on the other hand, he always felt "guilty" every day because of all the times that he's hurt me. But I told him that he has nothing to feel guilty about because I let it all go, him hurting me emotionally does not affect me anymore. And just recently he told me that he's starting to take interest in another girl. When I asked how he felt about me, he said "I know I like you, I just don't feel it". I got so confused because there were so many things happening with him. All I told him was to just focus on yourself before doing anything, even if that meant liking me. I've been very accepting of him wanting to be away from me. Whenever it gets hard, I do everything to help him. Whenever he wants space, I give it to him. All I ask is for him to be my friend. But I don't feel so appreciated. One time we were arguing about him feeling guilty so I left and told his guy friends to help him out because maybe he just didn't want to talk to me. After he said, "Why would you do that? I didn't want that". But then the next day he tweeted saying "Thank you to all my friends helping me out" I don't know what I should do anymore... I don't even hate him for taking an interest in someone else...
