Telling oh I no longer want to go as couple

[Hiddenaspie1973]

I've reached the end with partner of 23 years, but can't afford to leave and support 12 year old alone.
Joint mortgage, but not married. All i want is 50% of the profit from the sale of our first home (we both paid for 7 years). So 37500.
That will pay rent on a small home for 3 years whilst we could live off my earnings.
Once she's 18, I'll have to move 500 miles North to afford anything.
We've got his dads bday meal next Sunday at a pub. I no longer want to attend any family do's as a couple. It's a sham. He talks over me and our child. Even she tells him off about his selfish, ignorant behaviour. He also goes night fishing most weekends.
He'll go mad when i say I'm not going on Sunday. Any tips?

Just tell him straight. He sounds like a total selfish arse, why should you have to sugar coat anything for him? Would you be able to afford to use the profit from the sale of the house towards a deposit for your own house or flat?

Tell him asap, don't live like this for a minute longer than you have to, tell friends and family to make it real and your dd
