My husband (of 5 years) has always had a terrible habit of making contact with other women online
It isn't a habit, it's a conscious decision.
They were graphic and sexy- and what hurt most was that he was simply interested in these other women, engaging in kind conversation about their troubles.
Whoh! So he was responding in a sexual manner whilst being emphatic? Sounds like a sort of grooming, taking advantage of their situation? You also appear to have minimised his interaction?
The latest discovery knocked me sideways because I just naively thought he wouldn't go there any more since we have started our family.
Do you think you engaged in Magical Thinking?

I'm resentful and hurt and our relationship is not what I think we deserve.
You say we which implies he had no control over his actions and these things happen to him like he's a victim of circumstance? He did these things to you OP, he's done them in spite of you and your relationship.
He's gone to a counsellor and is on a programme for 'addiction'...I just don't buy it and he's stopped trying to explain it to me.
Do you think this is your gut instinct kicking in like 'you know' the real reason isn't addiction?
But he is doing, he says, all he can to make this better. I don't think I will leave him- but I feel like we're stuck in this sexless (because of my choice) relationship with a beautiful daughter.
What do you foresee happening when you're withholding sex from a man who appears to be looking elsewhere for sex?
