I broke up with my boyfriend of 1 year

Yesterday I broke up with my boyfriend of one year, after it happend we still talked but from 10-12 we were facetiming about what had happend and he made me feel so bad for dumping him, I tried to tell him we could be friends but he said he didn't want that and now I woke up missing him and regretting my decision, I want so badly to text him and ask him to take me back but I also don't want to feel the stress of being in that relationship and having to think about each action when it comes to being with him. It's hard because I saw a life with him in it and I still see it , and I'm missing the way he would hold me, kiss and hold my hand , basically I'm missing everything about him and I don't know how to deal and I'm pretty sure he hates me but then again just out of nowhere he would text me and say " I think we are better off at friende " and I kept having to anticipate when he would say that I hated having to put my walls up just as soon as they would come down. I need some advice on how to deal and if anyone else has been in that boat.
