I have been with my bf for 3.5 years but recently I have lost a lot of trust in him. I came across snapchat photos of a girl half naked + he was asking to see more. I confronted him, he said it was a girl he met on tinder when we were on a break last summer + he recently added her on facebook + they started chatting. They say it started just general conversation +got more flirty. He apologised said he felt bad + would never do it again. he also added his ex on facebook, he said he met her on a Friday night while being out + they got on, through messages from his friends it turned out he had spent the night with her but didn’t sleep together. He was getting stick from his friends saying why didn’t you sleep with her, he said it was because she would tell me. He also said how he forgot how much of a nice ass she had,asked his friends for her snapchat so he could ask for photos of her + how he wished he had of slept with her. I can’t help but feel really betrayed. We are still young + we do both love each other + I know he hasn’t actually cheated but I can’t help feel that i’m not enough. I don’t want to break up with him as we both want the same things in the long run +I do love him a lot. I feel we are together at the wrong time. I have been thinking about suggesting an open relationship to him but I don’t know if it will be the right choice. As we are still young there is a lot he wants to try by giving him this option will it help satisfy his other sexual desires by experiencing other women. I know my trust issues + insecurities are a problem but should I try something new
