Sleeping with GF's best friend
OK, so about 6 months back my gf and I decided to try a 3some with her best friend, who is kinda bi-curious. She even encouraged me to develop feelings for her. Shortly after though, my gf entered a depressed phase and started not being able to handle the fact i was f**king her friend, and we had to call the whole thing off.
Now my gf feels guilty about ruining it and has been telling me i should continue sleeping with her. I kinda suspect that she doesn't want me to, but i really like her friend now and she likes me too, and we took this as an excuse to restart. We both know we shouldn't, but once every 2-3 weeks we hook up.
Don't get me wrong, i can see myself marrying my gf, but i kinda wish she would officially let us do this so i can stop sneaking around.
Should we end it?
