My bf and I have been together on and off for 10 yrs. He has a brother and he has a gf that they've been together since we been together. I've always been jealous w/ her and my bf. I always thought they had something going on for no reason. I had no proof or anything. It was just me. And they stopped talking to each other bc I didn't want them too and made him delete her # from his phone. But today our daughter called from her phone to his phone and it showed like 30 text that were deleted so apparently they been texting like 3 time in the past 2 month. And he still lied to me about it saying he didn't know what that was he never talked her then after 5 min he admitted they have been texting but only 2x and he didn't tell me bc I would get pissed and make a big deal out of nothing It just in my head. He doesn't like her like that. He just sees her a sister and nothing else. He said I fucked up the relationship b/c I left him for another guy 7 yrs ago and that changed me. He thinks I'm scared he going to the same thing I did to him that he can even talk to her. He said they were friends even before we met and everything changed bc I'm to jealous. He also said his brother know that they talk and he ok with it bc he know there nothing going on. I really need advise do u think its just me, or is there something going on between them that they have to talk behind my back. Please help!!!
