A long term friendship is worth more than a shag like that..I think you did the right thing.
Argt WTF is that in your avatar?
had a similar experience ....best mate out of it though...so his g/f came on to me and well you know........anyway weeks later he starts gettin a bit strange and all ......think he had his suspicions anyway I chose to try and ignore it and we drifted apart because , every time we got together i thought he would bring it up (but he probably would`nt)
what i`m trying to say is that if you don`t clear the air wave good bye to a beatifull friendship .
btw she was an excellent exponent of the horizontal gymnastics
