I'd better give a bit of background here.
When I left ex-h my 2 dds stayed with me. A couple of years ago they both moved (at different times) to their dad's & are both still there. When I first met dh he did try really hard to get on with my dds who were then aged 6 & 7. Things were fine for a while but their dad kept telling them dh had nothing to do with them, couldn't tell them what to do etc & made the girls feel guilty for being nice to dh (although he was quite happy for dh to pay for all my dds needs while he did everything possible to avoid the CSA). Things unsurprisingly went totally downhill & have never really recovered even though both girls are now teenagers, realise their dad was in the wrong & are now okay towards dh (i.e. treat hime the same as they treat me, ex-h & their stepmum - they are teenagers).
I suspect that a large part of the reason dd2 moved out is the way dh acted towards her as he seemed to take dd1 moving out really personally & took out a lot of his anger on dd2 as she lived here for about a year on her own before following dd1 to their dad's. We now have another 2 dcs together & my dds visit for 2 nights every 2nd weekend.
Problem is every time my dds are here dh is a nightmare. He's sullen & very bad-tempered with me & my dds. He huffs & sighs if they try to sit in the living room with us until they get uncomfortable enough to go upstairs or if he can't wait for that he simply goes upstairs. He often ignores me & my dds when we try to talk to him or if he does respond it's just a grunt. He gets annoyed if I give them money - I insisted on giving them £5 each pocket money when they're here & he eventually accepted that but this afternoon when I gave them another 14p so they'd have enough to go along to the shop for a treat he sat & muttered & moaned. Then when they came back from the shop he wouldn't even let them in the living room with their ice poles & made them go upstairs. He claimed it was so dd3 wouldn't start howling about not having one but she was out cold on the couch! When I told him how fed up I am of the way he's treating them he grabbed his coat & left shouting that he's being driven out of his own house.
I know how hard he used to try with them & I know that he's angry at how devastated they left me when they chose to move out but I can't help feeling that he needs to let go of his grudges (he comes from a family of world-class grudge-holders) & remember that he's the adult. I can honestly see us splitting up over this as I feel torn between my dcs & my dh & I'm afraid there's only one way I can go
If you've managed to get this far, thanks for reading - I am a regular but have name-changed as I know people on here in RL.
