I can never feel jealous.
Ages ago my now ex wanted to see her ex "To see how times have been" - suprise suprise,. she dumped me for him. But that is not here or there.
My problem has always been that I can never feel jealousy. I never cared if my girlfriend wanted to go with friends, go out or came home slightly later.
Is it a problem? Do girls like if a guy shows a bit of jealousy? Should I just fake it to a certain degree? I usually show affection in other ways, so the problem should not be that they dont feel "Appreciated"
