I need advice

I left my daughter's father oct 30th of this year. Tomorrow will be 4 weeks.

This guy I've known since I was 13 so almost 10 years ago, messaged me not last friday, the friday before that. He basically told me hes always had feelings for me but the timing was always wrong and that since hes a few years older then me he wanted to wait till I was 18. Well then I got into a relationship and had been in one untill just recently.

I feel wrong? Like I'm cheating? This is the first time I've looked at another man in 4 year. I'm over my ex, that relationship was over along time ago, I just didnt have the balls to leave till a few weeks ago.

The thing is, he knows my family and they dont necessarily like each other. I feel wrong for wanting to see how it goes, but I also know that it sucks being with someone you're family dont like.
