what to do??

I met this guy a few days ago, he's 23 and I'm 18 almost 19, I'm currently pregnant(9 months to be exact). He doesn't care I'm pregnant or that I have a child on the way in fact, he loves kids. He's really cute, nice, and what not. But here's the thing; we were just talking and he said in the future he'd want kids and I'm like I'm sure you will with the right person and he basically mentioned me as being that person.. I kind of got nervous about it, honestly because like wow.. but I guess he said that because he wants to date me but I don't know if I'm capable of being in a relationship of someone trying to love me and I leave them because I feel like they are going to hurt me, use, cheat or whatever.. I have so many problems wrong with me it's so insane.. I would love to date him, but I'm scared you know?? And he said if I'm not ready to date then we can be friends but I feel like he got kinda upset by that.. but he has been trying to get to know me lately..
