I met my boyfriend on Tinder 4 months ago. I deleted it, but he hasn't. Yesterday, a girl snapped him while we were together and I asked him who it was. He gave me a rambling response about how she randomly added him and all that. They have a 6 day streak going. He's not protective of his phone and he did open it at my request so I could see it. It fucking hurt and now I'm questioning everything. I told him I didn't believe him and he said that he wouldn't cheat and that I was the one he wanted. Am I just being too trusting?
