jess, try turning it around. how would you feel if you found out sam were texting another guy and it was quite flirtatious and they were talking about having sex? and if she were to propose the idea of having sex with him to you and said it was "just sex". how would you feel if she did this?

i agree with whomever said that relationships do involve sacrifice. if you want to be with sam then be with her and let the other chick go. women aren't playthings jess. neither are we disposable. ask yourself if losing sam is really worth having sex with the other chick.
