I think its safe to say that my girlfriend has a boyfriend

As I sad, it started with just sex, but then she started staying over his house when nights got too late or she didn't want to drive after having a few drinks. She started hanging longer and longer the next day and they would do things that a couple would do. I noticed that I really liked it and have encouraged it. Now she goes over his house a few days a week and often stays over. Their sex is really hot and she often gets all dressed up for him. When they are not fucking, they are usually cuddling on the couch and watching movies. She even brought up going on a mini vacation with him for his birthday and they are exchanging christmas gifts this weekend.

I know this may sound crazy, but her and I are actually more in love than ever and I know that I'm number one and the love of her life. However, we have definitely have been enjoying the progress of her relationship with her other man! Who knew all the other stuff could be as much as a turn on as the sex!!
