Need help with relationship
I need help on my relationship, even though I haven't reach that marriage status yet. Me and my fiancee are engaged for a year now, and due to get married in July. We are living in different countries due to different job and have been in long distance relationship for 4 years (we have been together for 7 years). She is going to move back to my country (it is her home country). I am currently building a house to live together.
Since we are going to have the marriage her, we have been preparing since last year. However, since December she started to become lazy and she was busy doing her own activity (she has a religious group and go there very often). She told me that she had a project, and she is working on it (she told me all about the project).
The marriage planning is getting slower, and since we are going to have an oriental wedding with many guest (~1000 people) planning is crucial. She hasn't chosen her wedding dress yet (she kept postponing it).
About early this month, she confessed of cheating to me through skype. When this happened, I have just flown back from her country and I was confused and disappointed. She told me that she doesn't have any feelings for him and he is there when I am not there. She also told me that I am not listening to her as much, and she doesn't want to give details whether she has slept with him or not. She told me that I deserve someone better and left it for me to decide whether I want to continue with this relationship or not.
I just couldn't believe it until now that she has cheated on me. She is a very religious person, even though I am not as much. Now she is kinda running away by going to another country to go for a religious retreat and our contact has not been so smooth. I can't chase her because I am responsible for my work her (I run my own business). At first she showed remorse, but lately she has not shown any, and she told me to assume for the worst in her cheating part (means she has slept with him).
I am torn apart, I couldn't sleep properly and the thought of her sleeping with another person make my stomach sinks in really bad. My gut feeling is to cut off this engagement, however I want to do it gracefully and want to talk face to face to her. Any advice for me out there? Do you guys think that this relationship can be saved? Honestly, I can't trust her anymore and I am sure she won't let me go through her facebook/ phone etc.
