Did I choose the right one?

Kera
Do any of you feel that you chose the wrong partner? I'm worried I did, or even worse I'm just a terrible person. I'm always questioning it and feel alittle stuck. I feel like we have grown so different, we have hardly anything in common but our first little girl. I don't want to have to deal with a divorce. Our marriage isn't bad- he is a great person. We are just on different levels it feels like.
