I been with my FWB for 4 years now, during the weekend we spent some time together and he was looking through his phone and I see he has the tinder app. I didn’t tell him anything, but it did hurt my feelings seeing he was on that app. I know we are just FWB but a while back he had asked me if we can be exclusive. I am so confused. Is he allowed to go out with other girls and sleep with them?? We also go out a lot to concerts, events, movies out to eat. I really don’t know how to think about this. Please help me out.
