heartbroken, lost, confused, torn....

I'm married and I found out that the whole 5 years of our relationship, he cheated. He never stopped talking to women and never stopped presenting himself as single. I would catch him and he'd swear up and down he wouldn't do it again. Well I recently found out that when he'd promise those things, he was texting that person later that night. It isn't just women, I caught him with a man too. He had an emotional 11 month relationship with one girl. They never met in person but talked daily, sent pictures and I love you. On our weeding night and honey moon he was texting her. I stayed and forgave him because I have a seven year old(isn't his but been in his life since age one) no family support and I guess I'm just scared idk. My heart is broken and I guess I just need to get it out. No one knows from the outside friends family no one about all of this....
