With his baby? Besides all the financial and custodial issues, that could've brought back a flood of memories of good times & bad that he is having a tough time dealing with.

Not his baby? Maybe he's thinking about what went wrong with the marriage and realizing that he was more comfortable being divorced because she was alone.

I may be waaaaaaaaay off track here, but I'm not working with much info. Not that all the facts would help me. I'm a goofball, don't forget. lmfao
