My girlfriend and I broke up, she wanted to not me, because she didn't know how to deal with her brother leaving to go to the Air Force. We still very much cared for each other, but didn't know if we would get back together.

So I went out with friends to drink away my sorrows and be around people who care about me, I got drunk, I made a tinder. Now I want to be very clear that I never met with anyone, didn't exchange pictures, and barely talked to anyone.

Jump a few weeks into the future; Me and the gf are back together, and things are going great. Everything is back to normal. I haven't used tinder since a few days before we got back together, but I forgot to delete the app.

Her friend sees me on tinder, calls gf, and tells her.

Gf is now super pissed at me. AITA?
