I caught my lesbian girlfriend making out with one of her friends.
My girlfriend and I have been together for seven years next month and over the last two months she has been staying out all night drinking more getting in shape. She swears that nothing is going on and that we will be together forever.
Last night I went to bed again she went out came home at two in the morning with this friend and told me goodnight, and that her friend was going to stay over night. When I got up for work at 6 am I went downstairs to her room, and this girl was on top of her kissing her. I stood there in disbelief and they continued to make out. I went upstairs, and showered and got ready for work and my girlfriend came up, and I freaked on her and she didn't understand why I was mad. She said it had never happened and they were drunk .
What should I do? I am a girl by the way.
