I am a regular who joined somewhere between mouldies and penisbeaker, I have name changed but am most definitely not hairy of hand 
I don't want to drip feed, but I'll try to give you the outline without sending you to sleep! If you recognise me, please don't out me.
I have been married and holding together a blended family for over a decade. We both had DCs before we met, none together. The youngest two (one mine, one his) are late teens and still at home, one of them has a LO of their own.
When it's good it's great, when it's bad it's like a whole series of Jeremy Kyle rolled into one...
We went through a rocky patch that I thought would end in divorce over a year ago, but sought relationship counselling and seemed stronger than ever. The last few months have become increasing stressful, and the DCs attitude to home life has continually caused friction. We parent very differently. DH is the moody type who gets hung up on the small stuff. I'm more measured and reasoned, which he regards as patronising should I attempt conflict resolution with him. He is good at alternating between stonewalling and shouting 
It's obvious to me that we are back where we were a year ago. He cannot sustain the changes and has blown his last chance by making clear his increasing dislike and contempt for my DS, someone who he has lived with since they were in primary school. He says his main issue is DS not pulling his weight around the house, but given what I have tolerated and endured while still managing to love his DCs, there is no comparison or excuse.
We live in a HA property that I've been in for over 20 years. They will not house us separately in the event of us splitting up, and as joint tenants neither of us has more legal right than the other to remain. Technically I could attempt to join the waiting list but given we have been waiting for a larger property due to overcrowding for almost a decade, the chances of getting anywhere are zero. Leaving could/would deem me intentionally homeless.
DH and his DC could afford to stay if I left. I could only managed it in the short term if I could get him to leave- unlikely- as I would get tax credits as a single parent for the next 18 months. I work 4 days per week in a lowish paid job that I love. Having already started down this road before, I know the practicalities of housing were the biggest obstacle to getting out.
My amazing eldest and her DP have today thrown me a huge lifeline only a couple of hours after I told her how bad things are. They will be moving in the next few months anyway due to a job change. They have offered to rent a larger property to accommodate me and my DS. They have worked out that if I could look after my toddler GC for 4 days per week, the lack of exorbitant nursery fees would offset the increased rent. It would be for at least 2 years, perhaps longer, which would give me/us time to formulate a longer term plan.
I could work for 2 days per week term time- I know my company would let me, albeit reluctantly- and probably more in the holidays when she is off. We all get on brilliantly (I stay with them and look after DGC sometimes anyway) and I am daring to dream. She says me and my DS deserve to be happy, and I know she's right, but I'm humbled by her offer...
I haven't even had a chance to talk to my DS yet, he probably won't get home until after I've gone to bed.
Thanks for reading. I'm writing this whilst sitting in a room with DH who has not spoken a civil word to me today. He's chosen to spend the last 2 nights on the couch. I'm feeling very fragile but would really appreciate your thoughts
