I hate aim or any type of instant messaging >.< I just tell everyone mine isn't working and they leave me alone. Your mother's mourning phase is better than most. At least she's getting outside, you know?
My mom's been on two marriages this ones her last one. She gave up on love already. I wouldn't blame her for they both cheated. But I do know one thing. When I reach 18 I'll make my father suffer. Worst than you can ever imagine. :)
Just sign out of AIM. Say goodbye. Go on tomorrow.
My mom's the same way. Every time I think she finally got over this guy, she brings him up again, saying, "I miss marshell." I hate him so much. I only liked him 'cause he gave me stuff. But he cheated on like ten women, my mom included.
