"Detachment or Desperation?" - I think it's a little of both mixed together!!! I did the SAME thing when all of this first happened. I actually tracked down an ex on myspace and sent a friend request. I think I was feeling a bit low about myself and needed someone to stroke my ego. Nothing ever came of it, he is my friend on ms now but I barely chat with him and don't want him to know about my sitch with H. I think I also kinda did it in retaliation because H has female friends on ms yet out of respect for our relationship I never accepted any guys that I knew would upset him.
Yes they say really nasty stupid things, they are DAWAH!!!
