J in PA

I'm married for the second time and have discovered something very upsetting. My husband went out of town last night. He has a PDA and I discovered that he had emailed women that had posted very explicit postings on a website for the town he's going to. I called his cell phone and confronted him and he said he wasn't doing anything, and that he was just joking around. I feel like he was making arrangments to meet someone in this town.

Sadly, I had made a similar discovery about my first husband. That divorce was heartbreaking and I can't see turning a blind eye in this marriage if I wouldn't in my first.

It's more complicated because my current husband and I have a baby.

Can anyone give me some advice? Does every man do this? Or how is it that I've managed to find two that do. Or am I overreacting, as my husband says I am.

Thanks-
