NC for all this but I've been on these boards a millennia or so 
DFiance and I have been together 5 years next month. We've been through a few tough times (he was close with his exes and I had low self esteem, turned out his ex was a bitch who was trying to screw me over, we went NC with her, I have anxiety which causes me to have panic attacks in social situations which means his friends think I'm a bit crazy...) But genuinely it's been the best 5 years of my life and until last weekend I couldn't wait to marry him. I really can't imagine anything more amazing than getting to spend the rest of my life with him.
Last week I had to have a pretty serious gynae op that went wrong and involved me having a bit of a breakdown due to the insane amount of anaesthesia they had to give me and the feeling of intrusion when it went wrong. He was really supportive and moved meetings to be there with me (he didn't cancel his tickets to the cricket on the Friday which meant I was on my own for 48 hours in pain and sobbing, but I told him to go so I can't be angry about that.)
On Saturday it was our good friend's birthday and I had been crying on and off for 3 days and having a lot of vaginal bleeding. It was a picnic and I was really worried about going (I had a bit of a hysterical crying session an hour before) not least because of toileting and the fact I hadn't been outside yet, but I went.
At this picnic a casual joke was made about the stripper that had been at one of the guy's stag dos a few weeks back.
I had asked him about that stag do. He knows my feelings on strippers/sex work (briefly, I think it's sexist and exploitative, I don't believe in 'banning' grown men from doing anything but I couldn't respect a man who bought women). We have clashed on this in the past but I've accepted its more a political issue or ethical difference for us.
But he lied. I asked him last month whether there would be a stripper there and after whether there had been and he lied to my face. As far as I'm aware it's the first time he's done that and the trust is really broken for me.
Add to this that, due to the op, I can't have sex, baths, swim or use a tampon for a month. I'm a fat, bleeding, emotional mess. I'd psyched myself up to socialise on Saturday and all that happened was I found out that my 'oh he'd never do that' man was just the same as the bloody rest of them.
Since then I've had a really bad few days. I want him to comfort me and look after me post op but every time he gets close to me I remember that he lied about one of the things that's a line for me. He tries to hug my fat bleeding body and all I can think of is how he was willing to pay a woman to take her clothes off and lie to me about it. I can't have sex with him and they took 2cm of cervix off me in the op last week. I will never be as sexy as that stripper, and now he's just tied himself to a broken, sick woman who can't give him what he plainly wants.
He says he doesn't know why he didn't walk out, that it wasn't erotic, that he does respect women and he'll never lie to me again.
I reply - because you're weak, if it's not erotic then that's even more squalid, you don't respect women if you only respect women who aren't strippers (othering etc) and how the fuck can I know?!
I'm really vulnerable right now. I've had a botched operation on my reproductive parts at the age of 28 and I've been thrown into a low because of that. Plus now I have to deal with this lie.
Does anyone know how I can get past it? I want to trust him and love him and marry him. He's trying to be here for me right now. But I'm spending half my time trying to cling to him and half my time blocking him out because I'm hurt.
I'm in the worst depression of my life and I can't see the wood for the trees.
