Because dh is never proactive about suggesting things we can do as a family at weekends. It's always me. He'd rather moan and whinge about three weather/ not having anything to do.
I will be going back at some stage today, but I've had enough - every weekend right now is the same.
A bit of background. We have a 6yo ds and 4 month old dd. Ds is lovely, but quite high energy (or if not doing anything will just sit and watch TV or play or the tablet). Dh gets frustrated in both situations - ds is either throwing himself around the house hyped up, hanging around bored, or has his nose in technology. It can be a little wearing during the winter as i'm sure many can relate to. So we resolved to get out of the house more, which is fine in principle.
However dd obviously needs naps and feeds, so whatever we do has to incorporate her needs obviously. Yesterday I suggested a walk at the local country park. Dh wasn't exactly bowling me over with enthusiasm but we got out and had a lovely few hours. Dh and ds got on really well together and we worked well around dd's need for sleep (in the buggy) and feeds (at the cafe).
We woke up this morning and almost immediately dh began snapping at ds for various reasons. He took him out for a couple of hours for hockey, so I thought I'd think of something to do this afternoon as a family to stop us all tripping over each other inside. Thought we could go shopping for some gardening stuff and all get involved in the garden, tidying, planting etc. Dh's response: "It's freezing out there." No other suggestion of course, just negativity. So at this point I took umbrage and it turned into an argument. This is the second weekend running this has happened. He's not happy doing nothing in the house, but incapable of suggesting alternatives that take account of all our needs. It's so bloody wearing. I've ended up walking out on him and the kids and told him to tell me when he decides what he wants to do or when dd needs feeding (I'm breastfeeding) and I'll join him but until then I'm staying away. Childish perhaps, but I don't like arguing in front of the kids and I'm currently parked up crying in frustration. He's such a fucking mood hoover.
He sent me a really sweet text after I left and I'm afraid I was so angry and frustrated that my response wasn't very kind in return. I explained how I feel (which I tried earlier but communication isn't calm and reasonable when we argue) and told him I was pleased I'm not seeing him next Saturday (I'm taking dd to London). Now I feel awful and guilty. He unsurprisingly has to replied. 
Honestly he's a lovely man, but not always blessed with positivity or being proactive. But he adores me and the kids and 99% of the time is amazing.
I've been a shit to him haven't I?
