To say DH needs to stay home next weekend?

This is another one of those situations where it is glaringly obvious that this man does not love you, OP. By behaving the way he is, when you have asked him to stay home, he's actually showing contempt.

If someone you loved was in pain and needing help, you'd be willing to make 'sacrifices' (not that giving up going out is that big a deal). You would want to spare them pain, and would WANT to stay home with them to do that. You know that, OP. You know you would do that for him, or for the children.

It's what anyone would do for a person they loved. It's minimal effort too.

Therefore, he is loudly demonstrating that he doesn't love you.

Once you can accept that, his behaviour becomes completely understandable and your options become far more clear.

And if this lack of love is new for him, I certainly wouldn't discount an affair.

I would also hire a cleaner to do a house clean and get the van valet cleaned. And if the children are older why aren't they helping out?

Leaving you with all the housework, the kids, dogs, his new dog, even without a broken arm I wouldn't even put up with this. Even teens in a household should be doing their share of chores in the weekend and know to step up when someone is injured. He's an overgrown brat imo.

So you haven’t even got time to do everything you need for your business, yet he’s off enjoying his hobbies? Fuck that.

And I know you love your step-child like your own, but he’s the biological parent AND wanted a dog, so arguably he’s got more responsibilities at home than you do.

He needs to look after his dog. Or pay for it to go to kennels when he’s away.

I’d be furious with his selfishness.

If I'd broken my arm, there's no way my husband would be disappearing off for the weekend/days out with his mates. I wouldn't even need to say anything to him either, he'd know he needed to stay at home. In fact, he'd want to stay at home to make sure I was OK, and not doing too much!! Your husband thinks it's acceptable to go off every weekend doing his own thing, whilst his wife struggles with the children, every day tasks, dogs and a broken arm!!!! Your husband needs one almighty reality check. He doesn't get to disappear for weekends away, whilst you're struggling. That's inconsiderate and bloody selfish. Absolutely nothing wrong in having hobbies, but there are times when family comes first.

You are his servant and he loves jollies at the weekend which gives him time to relax!

It’s not about ‘help’, it’s about doing his fair share. So I wouldn’t make it about your needs but a general conversation about whether he thinks he’s pulling his weight in the relationship, household, as a partner, dad and dog owner. Interesting what he says.

How do you know he's not cheating?

Oh wow, I don't think I could be with someone like that ! Main reason is because you have broken your fing arm!!! Like hello where's the help with the doggies?! I understand his hobbies and going out etc but at this moment in time you need the most help and he's being selfish I cant understand it. So yeah talking is key.

He’s majorly taking the piss and I’d be telling him that!

What’s the point of you 2 being married? Is it just a childcare arrangement?

It just adds a bit more to the cheeky fuckery. You're also step parenting and facilitating his leisure time while he doesn't give a shit it would seem.

You're also looking after his child while he's out and about?? OP, that's a drip feed right there. The bloody cheek of him x

EDIT: He got upset when you said he couldn't go? Why is he upset about spending time with his family?

There was a thread a while back about a 'DH' who got upset about not being able to do his hobby one weekend......

This.
Or 1:1 hill walking with a friend who happens to be a woman who "really gets him"...

YANBU at all. He on the other hand needs a real reality check. You need to have a serious discussion about how he has a family and whilst the odd weekend day out solo is fine, then we majority of weekend time should be family time - and especially when you’re struggling with a broken arm! Plus, you get equal “you time”, so take it and relax.

OP, I agree with most of these comments. It's appalling how little consideration he has for you. However.....

Maybe with enough persuasion you could get him to cancel or curtail his plans. It could be problematic though. I'd expect resentment and accusations of you controlling him. Followed by him doubling down on his leisure time in the future as you 'won't need' him around now your recovered.

We see a lot of 'put your foot down' and 'sit him down' comments on these threads. The problem is, if you have to force him to prioritise you, then you were never his priority in the first place.

Ultimately he has already decided there are more important things than being home with his family, broken arm or not. You may get him to stay home by forcing the issue but you'll never make him want to.

Keep the dog. Rehome the man.

Leave early - Thursday. Send him a message to announce the fact that he will be in charge of the kids this weekend, and if you find out that he’s handed them over to his mummy and gone hill walking, you will be seeing a solicitor.

You need to rehome the new dog asap. Hes not going to step up.

He is taking the piss.

YANBU and are a pushover!
This can’t continue - you need a firm and frank discussion about how unfair he’s being. Put your foot down! Why not check into a hotel/ stay with friend Friday night if necessary - show him you mean it.

This with bells on.

OP - are you very sure that he’s definitely doing all these things at the weekend and who he’s doing them with? How is he on weekdays?
