I'm another jealous person, so I can sympathize!
Only I don't ever show it, because I'm also the type who tries to bury my feelings, especially if they don't make me feel good. I don't really know what to tell you...I've kind of had to adjust because my boyfriend has
a lot of female friends/acqaintances from where he's a bartender, so it's been really tough. So yeah, I just try to ignore it. I figure that it's better for me to keep it inside and deal with it myself than annoy him with, "Who's she? How do you know her? Blah blah blah..." Very UNhealthy, I know, but that's my twisted logic for you.
