I really need some advice about my relationship. Me and my partner have been together for 7 years. We have 2 children. When our first child was born around 1 month old I found out he was messaging another woman wanting to meet up, she was a bit apprehensive on her messages but my partner really wanted to pick her up and take her out. I confronted him, we argued and I ended up forgiving him. Since then and over the years I have found flirty messages to other women and also I found out he had an account on a swingers website and the pictures and messages have haunted me ever since. He was messaging other people on that site laughing at how I had no idea, that he had sex with all different women off the website and that he was seeking men and women on the site. I was heart broken and absolutely mortified. The messages were over the period of 6 months and i feel like such a fool, this happened around 18 months ago, we separated for a short while and sure enough I gave it another try. Another incident that happened was that I found out he had been sending inappropriate pics of himself to people on snapchat because he accidentally sent one to my SISTER! So of course they don't talk anymore. I'm emotionally drained, depressed and feel I am not good enough. I cry all the time and the trust and intimacy in our relationship has gone. Sex is out the window as I have caught him watching porn on many occasions so I feel second best. We dont talk and all communication has been shattered. I put all the deposit down on our house which was a lot but we have a 50 50 share as tenants in common. Can someone give me advice about what I could do if we were to separate. I'm tired of not trusting him and I just dont know what to do...
