Doubting everything post breakup

24 F, ended a 2 year relationship last week because he was dead set on children and because Ive never wanted them. I thought I knew that I don’t want kids. But honestly do I even know?? I only considered it because I met him and fell HARD. Until then, I've been dealing with my own issues (maybe I'm just not a very high functional adult???) and have never considered children. The idea mainly stresses me, but is that just because I'm negative and don't want to try anything that scares me?

Anyways, these posts scare me into thinking I’m never going to find someone as high quality as he is. He was loving and supportive and so adorably sweet to me. The horror stories make me doubt I’ll ever find anyone as good as he is. And my future is just cheaters, manipulators, and guys who will use me. It makes me want to run back to the safety of him. Help guys! I feel like there are so many loyal, sweet women. I feel like there are so few of him, and I let him go? What am I even doing
