I've been dating this guy for about 8 months now. We went to undergrad together and we fooled around there, but nothing serious. In the past 8 months is when things have gotten serious. He made the grad gesture of totally setting up a wonderful birthday for me with candles, balloons, dinner a hotel and so much more. I as well made sure his birthday was just as great as mine was and we see each other very often. As of recently, I've been feeling a little bit uneasy...he has been going out more, which is fine and I don't have a problem with that. But I saw that he still had tinder on his phone. I knew he had it a while ago before things started picking up between the two of us, but I thought it had been deleted. I saw the app on his phone and confronted him about it. He said it was from when he first started using it and he hasnt met anyone on there and he wasn;t interested. He told me that with his schedule, he barely has time to talk to me, which he makes work, so there is no way he has time to talk to any other girls. I did make a fake account and combed through it and did not find his profile...but I feel so uneasy still....what should I do??
