Hi Chatty
It's good that you feel ok about the baby, and I understand you would be worried too
I'm glad you had a good couple of hours but this is probably just setting you up for more disappointment if he is going to leave.
I'm not sorry he thinks his the bad guy. HE IS he is taking the what he thinks is the easy option to leave because he sees you and family life as dull. He seems to think going out and djing and all is more important, than having two adorable children and a partner that loves him.
The going out stuff doesn't last, you can't keep doing that your whole life. It will become boring too. What makes life intresting is moving on and finding new things, like having fabulous family holidays.
I agree that no one is perfect and maybe you both need to change a bit to make it work. My dh believes strongly in the book "Men are from Mars, Women are from venus" He thinks we are different and that men hate being nagged about housework etc, but will do it in an instant if you say what you want with out saying it in a nagging way, anyway it solved our problem so it worked for us.
I guess I'm trying to say you can work out small issues like this but only if the commitment is really there.
Would you consider moving if this doesn't work out?
