People are probably going to assume this is a troll post but I'm going to share an honest series of events here. Years ago I worked with two sisters who were older than me. The older sister, let's call her Jane left about 6 months after I started but her younger sister Amelia still worked with me. Jane was the fun type who liked to have a good time and had a wild side to her where as Amelia was an actual church girl who dressed conservatively but was very beautiful. Amelia surprised me by asking me out and we ended up dating for several months. She really did not treat me very well and would do things like disappear for an hour to go pray leaving me all alone, this left me alone with Jane and I got to know her better. Because Amelia was big on no sex before marriage I can also say that the physical part of our relationship was frustrating. After about 7 months of dating I had enough and I broke things off with Amelia. Over the next year Jane moved out and got her own place, I stopped by one evening with no intentions other than to say hello but one thing led to another and we crossed the line of friendship. At the time I did not feel too bad about dating Jane because in my mind Amelia had treated me badly so why should I let someone who did not treat me well stand in the way of my happiness now?? Looking back I think it was a bad idea to date sisters.
