I posted a few weeks ago about OH not coming home after a night out. Since then all was ok but last night after a family do he went to the pub to get fags and a pint. That was no problem, he also got a lift home from my eldest son at a decent hour so all was ok. Well when I got up I saw his phone glowing so I looked and there was a message from a woman saying "sorry no, am working sad face". I stupidly opened the message and he's asked her of she was out last night. Scrolled back a bit and there's a huge gap between that message and some from 2015. Probably deleted. The ones from 2015 were reminiscing about sexploits in their youth. Quite graphic and it was clearly him pushing the sex talk. I asked him if he was looking for anyone last night and he said no. I told him all I'd seen and he denies there's anything to it. I want out, I'm not waiting to see what shit he comes away with next. I have no money, I have up my business to have my 2 babies and I don't know what to do. How do you leave?
