Apparently me agreeing to swinging made me feel more relaxed around women at this playgroup he goes to and how before he couldn't talk to them because I would get jealous
Another load of bolleaux. He's been talking to them and I suspect that one of them has pampas grass growing rampant in her front garden.
I have no doubt that he's been planning this for some time and if you were to engage in swinging, if would rapidly turn to him having become overwhelmed by his attraction to an ow, so sorry, wish he'd never suggested it... as he walks out of your door to shack up wth her.
This knob thinks he's exceptionally clever in coming up with a plan that, if you were fool enough to chuck your car keys into the hat, would prevent you from divorcing him for adultery and, of course, he'd be able to threaten to use your swinging career to paint you in the blackest possible colours to all and sundry if you didn't acquiesce to his divorce demands.
I wouldn't put it past him to claim it was your insatiable appetite for sex, or curiousity about having sex with om, that caused poor put upon him to accompany you to 'adult parties' where he had no choice but to go with the flow, so to speak.
If you're planning to stay with your bf 'down the road', suze, make it clear to him that this will give him time to clear his stuff out before the the weekend when you expect him to leave your home for good.
