Hello Tomsmum. I am so sorry to hear you are going through this. Some of the other posters have mentioned someone else not too long ago posting something similar. Well I am sad to say that it was me, although I think I name changed,but as it was 2 years ago almost to the day I can't find it on here anymore.
I don't usually post on here but when I saw yours I just couldn't run.
It was the most shocking and disturbing of discoveries when I was at my most vulnerable. I had just given birth to our son,my mother was on life support and I was trying to look after 2 older children and a 6 week old baby. I found out by sheer accident that he had taken some naked snaps of me, nothing vulgar or sexual, and he had posted them on a dating site, setting up a profile of me in the process. Basically he was talking utter filth to men, posing as me and getting some kind of kick out of it.
He made all the usual promises and offered profuse apologies, calling it a game! He said he would get help as his frequent use of porn and his interest in no strings sites has caused major problems in our relationship. All of which amounted to nothing.
Fast forward to now and I can honestly say the last 2 years with him have been hell. I don't want to upset you or scare you, but I've learnt that men who get their kicks by behaving this way have absolutely no understanding of boundaries. Nor do they think they are ever in the wrong. As long as they aren't physically having sex with someone else then it's fair game in their eyes.
Decent people who love care and respect their partners, don't set out to deceive them, hurt them and they wouldn't risk wrecking their relationship or family life.
Please don't sweep this under the carpet, dig deep and don't be fooled into thinking this is a one off as in my experience it never is.
In terms of finding out if the photos have been put on the internet try and access his emails and see if he has signed up to any sites where this stuff could be displayed. That's how I found out, when I happened to see an email to him from Zoosk to say they had removed photos from a profile as it broke their strict nudity rules! I didn't have to look too far to find out what had been going on. If you find anything you must print it and keep it somewhere safe.
I know only too well the awful feelings you are experiencing so take care, confide in someone you can trust and keep on posting here. You'll get some good sound advice. I received plenty but thought things could get better and so tried to put it all behind me. It hasn't worked and only now after 2 years of more heartache, abuse and lies have I had enough. I'm planning my future without him.
Take Care of yourself!
