My husband had gone out to go do some shopping for the house. He came back with like three packs of pregnancy tests I thought nothing of it since we are trying to conceive. So I decided to take one since it's been a while since my period. (It's irregular so I never know what's up.) Well we use his phone for the timer to wait and he accedintally went to close his apps and I saw Tinder. I pretended I didn't see it because I didn't want it to be true. I just couldn't sleep so I downloaded it under my friends name (Yes I asked permission) I couldn't find him for trying for an hour. So while he was sleeping I decided to check his phone. He had deleted it so I redone loaded it and saw he was talking to some girl named Maria. It wasn't much but I'm shocked it was up under my nose.  For three days in those three days we where together visiting my father. I looked at his profile no indication of being married or anything says "he's not looking for much just friends and a drinking partner" but it's under the preference for women. This isn't the first time I saw it before but I thought my eyes where playing tricks so I ignored it. I'm so confused and hurt what should I do?
