I shouldn’t feel sad lol

I just started dating someone officially, we’ve been talking for over a month.

Now that it’s official, I feel sad lol my mind wanders when I’m not with him. I miss my baby & the family I wanted with his dad. he’s with his dad. He’s 6 months old. I left when I had found out he was seeing someone & cheating on me while I was pregnant. Idk why I feel sad. lol

The man I’m with is a great man, he’s funny, kind, hardworking, a family man. I think I’m sad or scared because this is new to me? Idk. How do I get over this feeling.

** I didn’t leave my baby. We are doing 2 weeks co-parenting. It’s dad’s turn. Baby just left me 2 nights ago.
