Ok, here goes. I'm going to tell a story that I have never ever confessed to anyone.
My husband has always known my strong views against lap-dancing places and the like. I think they are a vile reflection of our society's lack of basic morals and family values. This is something he knew about me way back in the early days of our dating relationship.
Fast forward several years, and we have an 18month old daughter and are getting married. So of course, up comes the obligitory stag night discussions. He goes for 1 night away in the UK, staying at a mate's house. He promises me faithfully that the night will not involve anything seedy. The next day he comes home, tells me all about it and again promises me faithfully nothing untoward went on.
I find out about the lap-dancing place ON OUR WEDDING DAY. I overheard a conversation between by husband and a mate. He saw me listening and his face dropped. This was during the evening do. I somehow carried on the rest of the night pretending I hadn't heard anything and didn't ask him about it until the next day.
So the next day, in our penthouse hotel suite he confesses all. The lap-dancing club and the £30 he paid for a private dance (during which she took ALL her clothes off I didn't even know they did this).
I was in pieces for A LONG TIME after this. I mean total breakdown. Crying for days. Screaming at him. Even making myself sick.
In fairness, he tried and tried to make things better but nothing could console me.
I understand exactly what the OP means when she says she loves her dh a little less. That's how I felt. I was totally repulsed by him, our sex life went out the window and of course every ounce of trust went with it.
In the end, he booked us some Relate sessions and I agreed to go along. This was nearly 4 years ago now, and as ashamed as I am of this story, I'm proud to say that we worked through it and probably now have a stronger relationship than we had before.
The only way we have managed to do this is by him REALLY realising how much he had hurt me. He stopped going on any nights out at all because he knew he had such a long way to go to build that trust back up. When I saw the commitment he was making to fixing things, the trust did gradually come back although it did take literally years.
I think the whole thing changed him a bit. Maybe he realised how close he came to losing everything. Now he hardly ever wants to go out, and prefers to be at home with his family. An old school friend is getting married this year and he's already said no to the stag do partly out of respect for me and partly 'cos he's not really that fussed on going anyway.
To the OP, I'm so sorry you are going through this now with such a young baby. All I can say is don't try and hide your feelings. Surely it will only fester away inside until you reach some kind of breaking point? Your dh needs to know how deeply he has hurt you. How else will he be able to put things right?
