Hi turtle!
I have to admit, I can't imagine my DH ever taking DS to a playgroup or similar. It's just not going to happen and I think I'd drive myself (and him, and possibly DS!) demented trying to force it.
Even this morning, I took DS to the swings and to feed the ducks. I wouldn't naturally expect DH to come with us. I suppose because DH was working away so much, I've learned to do things on my own so it bothers me less now he IS at home, IYSWIM.
I'm certainly not going to call your DH a t**t or anything similar, but I do agree that if he doesn't want to help out with the housework, then he should be paying for help for you. I haven't needed help with DS, but do intend to get a PT nanny or housekeeper once I have two DC.
I've only skimmed the replies, but from what you've said, it does seem that you two have talked about the issue, so perhaps it would be worth taking a bit of time out / think outside the box. One thing I refuse to do is not do the things I want to with DS - so we do go to the swings etc., even if it's just the two of us. It's still good fun and we're happier coming home and DH is happier because he's had an hour off... Not sure if that's something to consider (For me, DH is great at sorting the house etc., so when we do go out, we are certain to come home to a hoovered / tidied house). Are there any jobs your DH DOES like doing?
One thing I can say, is it is almost certainly likely to get easier. My DSDs are 11 and 14 now and DH is BRILLIANT with them. even though DS is only 12 months old, they def. do interact more now than they did when he was first born, so I do believe that will continue as DS gets older.
I'm also lucky that DH takes his responsibilities seriously (provides well for us etc) and it's always positive to look at the good things, isn't it? Can you make a list of all the things you like about your DH / all of the good things he does?
Not sure if any of that is any help.
