If its not for you, its not for you. There's nothing wrong with it!

I won't ever date someone who has a child. Nope, not for me. (Oh, and believe you me, I've gotten so much shyte for this it isn't even funny!) But, the truth is, that I know me, I know my own personal struggles, and I'm not going to put all of that on the back burner for someone else. If it means I stay single as I've just cut out a portion of the dating population, then so be it. (As someone with a severe disorder, I won't tolerate being a low priority.)

Just be honest with yourself. Since you're in your early 20's, there are a TON of single men out there who don't have kids yet. If you can't see yourself as a step-mom, do the right thing and let this guy go.
