My wife slept with another man while on a break but found out she is pregnant – is it mine?

DEAR DEIDRE: MY wife admitted she slept with another man while we were on a break. We got back together when she found out she was pregnant.

The baby could be his or mine. I’m 42 and my wife is 38. We’ve been together for 12 years and have two daughters.

We recently went through a tough time with my wife telling me she needed some space.

Reluctantly, I agreed to move out, staying with a friend for almost four months. We kept in touch and saw each other regularly...
