Probably a totally irrelevant rambling but why do children have to be first or step mum second? I know we have a thankless task but to think that ul never be a top priority in ur OHs life makes the whole thing pretty bloody pointless to me..?
Just like OP in our house it I didn't cook, clean, shop, organise listen to the bad day at school or favourite band there wouldn't be much of a family here at all! OH might have created dsd ( obviously artificially ex is gross!) but we both have done a lot as OP has over ten years and his home/ lifestyle etc are atleast 50/50 down to me!
OP has created a home that these boys want to stay in. What would happen if she wasn't contrantly picking up the pieces?
My OH is useless on his own with dsd and the house although would never admit it. He gets unpleasant sometimes when she's here because it's a big fat disappointment too him how their relationship is, her behaviour and how her upbringing has been. This makes him very defensive. Are you sure your not experiencing the same on a daily level?
Again maybe a bit simplistic but my OH will snap at whatever's obviously causing the conflict ie me kicking off before dsd/ MIL or anyone else whose caused my reaction?
I'm not saying its easy at all and I would hate to be in your shoes but I have decided in our house we are coming to the end of this crap and it's worth digging in. It sounds like you have had an amazing relationship in the past and maybe if the above is true your OH just doesn't know what to do either?
Could u have a couple of days away or even a night away? We have had a week off and the perspective is amazing! If one is off to uni I'm sure the other will be a bit easier to deal with than the two?
What about camp America or something like that? Could you sign him up for something to get him gone for a few weeks that he would enjoy even if it cost some money just to give you a much needed break? Something that might make him grow up a bit?
Sorry if it all sounds like junk but I'm seeing my situation very differently after being at braking point for a long time and I've detached the relationships between all of us and the one between me and OH and am feeling much better. Even if u send them for a pizza and cinema create some alone time it's worked wonders here. It's not rewarding bad behaviour it's rewarding u!
What about the inlaws? Can they help? I had a word with MIL and she took dsd last weekend and it really helped she had no clue how serious things were in the house and I felt better for telling someone..
Really hope you can find a way through it's a horrible lonely place sometimes.. Try just for a few days to not comment or react let them be the ones causing the obviousl agro it certainly works in our house the focus shifted from me going mad to the other people causing the drama..
If all else fails why not have a day/ day and night away yourself there's tonnes of cheap deals just give yourself a break. Hope u can sort things OP and of course you are very important to your OH ignore the above nothing's ever that simple :)
