I've read PC a lot and the advice is awesome that everyone gives so I would like to share my story.

I was married for 5 years (no kids). My mom was diagnosed with cancer and I moved in with her to help her get to and from chemo. My husband was completely understanding. He let a friend of his move in while I was gone and he started smoking pot again. His step-father died and he moved his mother in the house too. We started arguing a lot. His mother was then diagnosed with Huntington's disease. I don't know what I was thinking, but I started seeing someone while I was still married.

I told my husband I wanted a divorce and it broke his heart. He wanted to work on things even after I told him that I had cheated on him. He refused to sign the papers for months and kept trying to get me to reconsider. My mother was pushing me to get a divorce, even though she loved my husband, because my new love interest was in law school and that was more prestigious than what my husband did (meat manager at a wholesale club).

After my mom died, I moved in with my love interest who is now my fiance. I have not properly grieved for my mother and I am going to therapy for some issues that I am dealing with because of her. I don't know if it is because of my loss that I am sad or I don't know if I've made a mistake.
My fiance is a very negative person. I have become a very quiet person because I don't want to hear his negative comments about whatever I say. He used to make fun of me in front of his friends and he deliberately tries to make me angry. I told him that it hurt me when he did this but he didn't change. Last December, I told my sister and brother that I was unhappy and I was thinking of leaving. I left in February and met someone else the same month.

My fiance completely turned around and promised he would change. I still loved him but I also had a new person that I liked. I made the mistake of keeping both of them for a short while in case one didn't work. My fiance was a completely different person-he was back to the person I fell in love with. The other one was too far away but I kept talking to him anyway. My fiance found out (I wasn't engaged at this point because we had just gotten back together) and I agreed to break up with the other one on the phone in front of fiance.

Now, he constantly brings up this other man that I had a very brief relationship with. It was wrong on my part to even think of having a relationship so quickly but I had dealt with so much negativity and low self-esteem and this person was so positive and caring. My fiance makes snide remarks to me about being a cheater. Sometimes he does this in front of others and so I have stopped going to social events with him so I don't have to deal with it because it makes me feel horrible.

I still talk to my ex-husband because we are really good friends but I don't talk to him as much because I know my fiance does not like it. My ex-husband told me that he wants me back. I have been divorced for over 2 years and my house is the same as when I left...he hasn't changed anything and my clothes that I left behind are still hanging in the closet. A lot of my friends are mutual friends with my ex-husband and I've stopped hanging around them. I am now completely isolated from my friends because I am trying to make this relationship work...but I am depressed and unhappy. We have our good times but it's nothing compared to the good memories that I have with my ex. I miss my friends and my house and my ex-husband. I don't want to make a rash decision in my state of mind. Can anyone give me some advice that will help me?
