I agree with Anita. If you feel physically ill, listen to that.
I’ll pass along good advice that I got from my mom ages ago. She was a single parent and always told me to only date men that would make good parents. Because you never know, they could end up as the father of your child. I always kept that in the back of my mind and it was a good way to judge if someone was worth being in a real relationship with. Now I have a good husband who is also a good dad.
Also, I’m sure this guy has positive attributes and a lot of potential, but look at the decisions he has made and the direction he is taking his life in, not just what he is saying or could be doing. Actions speak louder than words.
