It's not really "wrong", it probably just makes your girlfriend feel uncomfortable. You used to be with
that girl, so she might be afraid you might decide you want to be with her again, maybe by speaking to them you might
rediscover old feelings...
Jealousy, just means she cares, or she's insecure and afraid of losing you.
If she didn't get jealous then she probably doesn't care about you so much, or else takes you for
granted.
I know that I feel very uncomfortable with the idea of my bf spending time with other girls, though I do trust him, and
know he's faithful...just as he would feel uncomfortable with me spending time with other guys, though I usually
feel uncomfortable with other guys anyway...
Luckily I don't really have to worry about ex girlfriends, because he hasn't really been with anyone
else.......
The main thing is not to see girl - friends without your girlfriend knowing, no matter how innocent, you may think it
is, if your girlfriend finds out from anyone other than you, or if you don't work it out, she'll be bound to
think you're cheating, even if you know you're not, and get really upset or angry.
Sometimes, I guess, it's not good to stay friends with your exs...
I know that if me and my boyfriend break up, he said that he didn't want to stay friends, because it would be too
awkward or something...kinda depressing really...because I feel really close to him, and wouldn't want to lose him
completely if we had to break up...
