I have been friends with my friend for 15 years. We are both females, both in our mid 20's. We are friends on Facebook, both have kids, etc. She came down this weekend from Oregon and her and I and another friend (a man) all went out to dinner, then a movie. It was supposed to be just friends going out together. At dinner the two of them had nothing but sexual innuendos across the table and talked about what they were going to do to each other after the dinner/movie. After dinner we went to the mall before the movie, and another friend (a woman) joined us. We walked around the mall, going into shops, the "frisky" ones kept ducking into the hallways, making out in the middle of the mall, etc. When we actually got to the theatre, the "frisky" ones had their hands in each others crotches, down the pants, etc. I felt disgusted, and embarrassed. I feel like she has changed, and who doesn't change, but at 27 I feel like she is someone I do not want to associate with. I do not drink, or smoke, or f***k everything that walks that I can get my hands on. I also do not stay out all night long and have someone else watch my kids for me. I feel that she is completely opposite of who she was, and I had no clue she was like this when we have talked online. My last straw of disgust was when she asked me to join their threesome, and when she kept talking about how "last weekend" she was out, drank until she couldn't remember anything, and then drove home and remembers nothing about how many people she slept with or how she got home. I may sound judgmental but at 27, if you choose to have kids you should be responsible for them, and not party every night or drink until you can't remember and sleep with anyone and everyone.. I am wondering if me thinking that we shouldn't be friends anymore is a stupid decision. I mean I feel like we have nothing in common anymore and I think that she isn't being very responsible.
