I’m going to try and keep this short and to the point. A month ago my DS(18), had suspicions about my husband (his dad). He checked his phone late at night and found a WhatsApp chat with a woman from my husbands work and hundreds of photos, including nudes and photos of her and my husband out in London among other places dating back 18 months. He called my husband the next morning at work and told him he had to tell me or my son would. My husband called me and told me he had made a mistake and had sent her a nude photo (my son didn’t tell him that he had taken a video of all the photos). Husband tried to say that he was just helping her as he felt sorry for her, and the one nude photo was a stupid mistake. At this point my son hadn’t told me about the photos. After a few days, I started to question it all and then my son showed me the video. My husband still tried to deny everything, saying she was an alcoholic and he was trying to help her and then she tried to blackmail him by saying if he didn’t send her photos and keep chatting to her, she would tell me he had slept with her. Obviously I now don’t believe a word he says. It’s laughable the reasons he is coming up with as to why he sent her several nudes, took her to the zoo and bought her stuff(I have the screenshots of email orders). So, I have seen a solicitor. We rent and have a house deposit in my savings account. We have been married 25 years, 2 kids. My son hates him. I have tried to keep most of it from my DD(12). I told him Friday that I don’t want to be with him as he has lied for over a year about where he has been, who he was texting everyday and the photos. He went crazy, won’t talk sensible, says he will take me to court so that I don’t have much money left after legal fees and that he wants to stay with me so it will be my fault that the kids lives will be ruined by living in a smaller house and having no money. He will not listen to reason. I have a decent job, I know that if he lets me have the deposit I can provide a home for me and kids. I’ve even said that I wouldn’t ask him for anything if he lets me buy a house. He point blankly says no and he will see me in court. We have no choice at the moment but to stay in our rented house. Any advice would be gratefully appreciated.
