You're all right - all I've done is text him all day and shown i'm not really leaving, which now makes me look a complete tit and I've lost the upper hand completely because i've essentially just thrown my toys out of the pram.
I wouldn't focus on that. Most of us here, married or not, have had a melt-down in front of our other half. It means nothing.
I read a tip once for when you feel you've made a twat of yourself with a bloke: picture a car who just fell off a wall. Does it panic, stammer, try to explain why it fell off? Does it scrabble around trying to regain its coolness? Does it talk about it? Nope. It just gets up and carries on like NOTHING EVER HAPPENED. Be the cat now. Don't sit down for yet another talk.
He definitely knows where you stand now! So if he doesn't produce a ring in the next month or so, he really REALLY doesn't want to.
The thing about his ex proposing to him is telling. He obviously just isn't someone who wants to be married. Not with her and apparently not with you. It's not your fault, it's nothing you've done - he's just not into the whole concept. I'd feel relieved that his ex had to drag him up the aisle. At least he wasn't proposing to every other woman on earth, except you.
His view of marriage is not a judgement on you.
So you've had a hissy fit. Draw a line. But take steps to disengage. Actual steps. Don't say "Well, this was a close call and I think I should get a job sometime soon," but then get so sucked back into all the chores and childcare you do for him your daily life that it all slides away. You have to harness how you feel NOW. And take ACTION.
The first thing you could do - and I really would do it, because it will change how you think - is buy and read this bookk*. It's the very best "build a backbone" book I've EVER read. And your situation is in there. She tells you what to do.
You are awesome.
He hates marriage. Not you. Marriage.
I don't know what will happen, but I know you'll be ok because you are lovable, kind, generous, warm-hearted and probably absolutely gorgeous too. You will be fine, with him or without him.
