Give in to conceive?

Kendra
My boyfriend and I have talked about having a child of our own in the future but it really scares me. 
​ I have a son already with a guy that doesn't do much for him and isn't, in the nicest way to put it, a stand up guy. I'm just scared to go through the same thing with my current boyfriend as I did with my last.
​ What if he gets scared? Or finds someone else while I'm an emotional wreck? I don't know if I could go through it all being so paranoid.
