Its not jelousy, its called common sence. Be glad you have it.

I dont trust it one bit neither btw. It doesnt make sense. I asked my fiancee, and he is throwing up the "OMG RED FLAG" Sign.

Dont let him go, and tell him that its horribly rude! Hell, ask him how would he like it if you just went up to meet some "old friend that was a guy and we are randomly going to DINNER"....

He wouldnt like it so much.
