I go to college 3 hours away from where me and my gf live so I stay in accommodation up there and only see her on weekends. She was working Friday saturday Sunday and Monday(I had no college monday) so I only spent 3 hours with her during the whole weekend. I had a dentist apt at 2.30 at home and I was gonna get the bus to college after that apt and me and my gf were free all morning (she had work at 4), so she went into the city to do some shopping and I met up with her in there. We were together for 30 min which she spent shopping for clothes (it was her only chance to do some shopping) and I had just bought a pizza slice and say down with her when she said she had to go meet her friend to buy her friend some clothes for the event they're both going to, and gave me a few kisses and left. I was pretty annoyed that she just got up and left because imo she didn't have to meet up with her friend at all she just chose her friend over me. She says she's not superwoman but I don't think I'm unreasonable for expecting my gf to spend more time with me. AITA?
