I had that one guy with whom I had an history or affair in the past before meeting my boyfriend. When we started relationship I had kept communication with that one guy but stayed as friends and he started to reveal his feelings when I was my boyfriend. At first I didn't tell my boyfriend about my past with this guy but one day when he was asking and revealing I too wanted to be honest with me him and tell him about my past with this guy. then he broke up with me but later we got back together. He wanted me to cut all communication with him. What we did at some point. During the relationship had some stressed situation that I couldn't handle about marriage and all, my mom was so excited and I didn't want to deceive her, my dad totally against I didn't want him to get points on it and my best friends too were so glad and one ask to be my maid of honour that I was scared to deceive them. I tried to speak to my boyfriend but it was like either now or that I'm unsure about the relationship so I couldn't talk about get stressed. Was thinking of ways to get into hospital or going into coma for some days. I didn't know to whom to talk about it so I spoke to this guy with whom I stayed friend but had affair before, we went to the city I left my boyfriend that day to meet him and talk about this I eventually cried all long with him, and he said that I should happy few days before my marriage and not be like that and tried to kiss to console me but we didn't as I couldn't accept it, but he understood it. And one day he phone my dad to talk about my plans. 4times during the 10months I met him, and keep communication on phone like it was a girlfriend I was talking to. My boyfriend discovered and now I lost all his trust due to communicating and meeting guy he hates. What he doesn't know is that he is actually sick and have incurable disease that he needs to go abroad. My boyfriend due to my past with him have doubts about me thinking I cheated but didn't.
