Is it okay to take my baby

To go meet up with my ex boyfriend? We’re contemplating getting back together. I’ve know him since I was 16 , he’s such a good guy. We were supposed to have our first kid together but then I met my daughters Father and kinda shaded him. But I think he’ll be a good influence in her life. He’s naturally a sweetheart but I never seen him around kids, so I don’t know. I’m also concerned because my daughter is 8 months and hasn’t said Dada and I don’t want him to be around her so much she starts saying it to him. She hasn’t seen her real dad in almost two months. Which a long time for a baby under 1 and I can’t control what she says at this point. I just wanna think a little further down the line because if I meet up with her the first time it’s bound to become a habit. Any thoughts?
