I know how everyone feels here. Sometimes I thought it was just me but it would appear not to be the case... For the past year and a half I've had the same troubles with two girls I got to know. And believe it or not we're all in our 20s so even beyond high school the cattiness and silliness doesn't stop with some women!
The first got to know me and she couldn't stop telling me about her problems with her current bf - I listened, I advised where I could and I tried to be there. Then I hit a wall with something and turned to her one night. She listened, we chatted. But after that night she went very cold towards me and ignored/avoided me a lot - it was almost as if she'd realised I was only human too and therefore if I were to have problems she didn't want to know. Great.
The second girl I got to know recently was a very similar story. I made very sure not to ever tell her if I was having a bad time with something in fear of her doing the same. But all the while I was making another mistake. She had just had a bad breakup and spent all her time talking about him or the guy she was now falling for. I listened, I helped, blah blah blah. Then she took it upon her to start treating me badly when we went out with her friends. Several strikes of her being completely unreasonable caused me to cut my ties and walk. It was a big slap in the face after all the hours of her draining me dry about her issues. And I mean I'd listen sometimes for 4 hours at her going over and over on the same stuff. It would appear I allowed people to treat me like a counsellor/therapist but I haven't gained any respect from these girls.
A similar girl I knew used to only ever want to meet up with me when things were going wrong in her life. I only began to learn the pattern after a while, but she never thought to invite me out with her gfs and go out on the tiles. The last time she rang I never picked up the phone.
Consequently I only have 3 or 4 genuinely close girl friends but they're all from different circles which means we never go out on girly nights out
I have more male friends really. They're so much easier to deal with, there's no psychology, silliness, bitchiness or anything but as you girls say - it's never quite the same.
I'm consequently very guarded now around new women and I don't make any effort to get to know them better other than chatting to them on the night in question, but I won't ask them for their numbers or anything and suggest meeting up together on our own to hang out. Sad really but there are too many insecure women out there that need to grow up a little - I can usually tell these days if a woman's going to be needy now and I smell it a mile off...
