Fiancé of 6 years, not sure how to go on
I have been living with my fiancé for 6 years and we have had our share of issues since being together. In 2007 and 2009, I caught him having at best emotional affairs (proof in IM transcripts and text messages) and probably physical affairs with several women. He used to be in a job that required him to travel frequently, and he met many of these women in his travels. In the last four years, I have gradually built my trust back up for him and thought all the cheating and lying was behind us. I began to truly forgive him and believe that it was just our young age that caused the problems in the beginning. I was 19 and he was 23 when we moved in together in 2007.
Well, yesterday I found him sitting in a car in a parking log with a woman alone when he told me he was at work. I just got out of the hospital two days ago, I have had pneumonia for two weeks and he seemed distant. He told me this woman was just a friend and that he hasn't told me about any of his woman friends because he thought I would overreact. I told him that of course I feel jealous and suspicious because of our past. He agrees that he understands a little and seems somewhat apologetic.
I went home and checked our cell phone account records and he has been talking to this one woman everyday on the phone for at least 15-20 min and has been texting her 30-40 times per day. To me that seems excessive for a friend.
I am trying to move on from what has happened, and I was able to talk to the girl who seems genuinely just a friend, but it still is making me so depressed and helpless feeling.
Do you think that I should keep trying to believe that this is just a friendship? Do I have the right to ask him to stop? I really love him and just wish we could learn to live without all these lies and suspicions. I feel so let down after finally believing that these types of problems were behind us.
