So my boyfriend had went and hung out with his friends and his sister the other night (or at least that might he said friends and his sister) which is completely okay, but he had said today that it was just him and his sister, so I had said "I thought there was friends but it sound like you had fun" and he completely ignored my first statement. I know I'm probably over reacting but my mind automatically goes to when I was cheated on in previous relationships, which in one of the cheating the excuse used was that he was hanging out with friends.. Any tips on letting go of this stuff so it won't effect my current relationship?
