I agree with sherryinutah - if you are financially dependent on this person setting the relationship aside it would be good for you to regain some independence so you have a foundation to start anew if that's what you choose to do. I was only married 12 years when I divorced for the first time - cheating, drugs, alcohol were all involved. Pregnant with my 3rd child I decided I wasn't going to raise another in this environment. They and I deserved better. I just ran into a nurse who was married for 40+ years and she found out her husband had cheated on her with prostitutes most of there marriage. She said they had a nice home, beautiful family, vacations every year and lived out the American dream. All she ever wanted was him though...now nearing retirement she realized it didn't matter she would rather be alone than have the thought in the back of her mind of having to share him. I hope you are able to come to a healthy decision for yourself.
