i'm 4 years out, but we're still not divorced legally.. very much living seperated lives though, and i consider myself single.. divorce is pending.
i had one foot out the door for quite a while, my ex was emotionally and sexually abusive towards me, constantly harassed me, tried it on in my sleep or would grope me around the house, called me all kinds of names, tried to isolate me from friends/family... all while telling me that i was the abusive one because i wouldn't sleep with him...
The final straw/crunch moment for me was he told me i couldn't go somewhere i wanted to go, one week after he'd spent a whole weekend on a boys thing with his mates.. i wanted 1 afternoon. We rowed about it all day, then in the middle of the evening he told me i must be having an affair (i wasn't) and what an awful shitty person i was. I ended up sitting there, seething, trying to be grey rock, trying to ignore his tirade, and i just snapped, i screamed back 'I don't want to be married to you any more"... i think i shocked myself that after YEARS of wanting to leave, but never having the courage, i finally found my backbone.
I left 2 days later, family came while he was at work and moved me and the kids out, lock stock and barrel in one day... took everything i could get in.
Haven't looked back once. Was it hard? Yes.. but that was mostly his behaviour, he got nasty/more abusive, then tried to get more controlling, stalking my social media.. etc. Outside of his idiotic abusive behaviour, it was honestly the BEST decision i ever made.
We get on ok now, i'm still wary of him, i'm still his verbal punchbag if something else upsets him.. he'll pick a fight with me, but i just ignore him now, thats who he is, he's pushed friends/family alike away.. but we co parent well enough.
I now have a social life, the best friends i've ever had, and i'm the happiest i've ever been. (mh issues aside from being in an abusive marriage for so long, but i'm working through those with help)
So.. i guess my message is, if you're still hesitating, still wavering.. make the break, do it, find your freedom, its worth the initial stress and upheaval, i promise, don't waste any more of your life on a marriage/relationship that isn't serving you or making you happy.
