Long story short suspected DP of 20 years has been cheating on me for several months now. Works away from home so has been difficult to prove. This weekend found things on his email ( nothing as obvious as messages from another woman) but enough to know that he is lying to me. Confronted him by phone call - working away again. Hes come up with some BS story for what ive found and has swang it round so its my fault for questioning him all the time - has not spoken to/messaged me since yesterday when he sent his BS story to me. Is coming home tomorrow and i know hes gonna try and make everything my fault and try and make me believe what he says. I know i have to end it - i dont believe a thing that comes out of his mouth- have caught him out lying several times before. The trouble is i still love him despite everything and the easiest thing to do would be to believe what he says to take the pain and hurt away. I have to stay strong- i know hes been cheating- how to i do this.
