I'm not sure that there IS anything that can be done. Look at real life... people do the same thing all the time. As an example, one of my friends was interested in a guy who was doin the whole attention giving thing, and acting like he was really into her. She asked me what I thought of him, and, stupid me, I actually told her. BAD mistake, because I didn't trust him as far as I could throw him and told her that in my opinion, he would stick with her until he found someone he thought was better, and then dump her. Of coruse, she got totally pissed at me, very upset, and stopped talking to me for about a week. A month later, he dumped her for someone else. Please give me kudos here, I did NOT say I told you so. But she got mad at me all over again because it had turned out I was right. Another time, a different friend... so head over heels in love with a guy that she wouldn't hear anything negative about him... soooo... I had to stay quiet and wait till he screwed her over....which he did. When she asked me why I didn't say that I thought he was bad news, I asked her if she would have believed me at the time... she had to admit that no, she wouldn't have.
I guess that's my point... when people decide to jump off the deep end, a lot of them seem to leave their intellegence and common sense at the edge of the pool. I'm as guilty as the next person... my *ahem* ill fated FCing for example... all three of them. What bugs me is that those same people get all upset with everyone else after everything is overwith, asking "Why didn't you tell me to stay away from him/her?" The answer is, "Because you wouldn't have listened and would have just gotten mad at me."
My two cents worth is, be adult to admit you made a mistake about someone, and go into the next relationship wiser and with your eyes wide open. Don't assume that just because a guy is flirting with you, that he wants to FC you... and visa versa. There are people who are unscrupulous... horrible, but true. They will use you if they get the chance. They need that sense of power. Are they scumbags for doing it? Sure they are, but it doesn't mean they aren't going to do it. We are Proud Tuchuk Women. WE need to decide that WE are worth more than just a little flirt. A guy has to PROVE himself before we take any flirting seriously. And, if we are needing love and affection so desperately that we will fall for any guy who does flirt with us, and again, I have been guilty of this myself... (thinking of a certain urt who Fc'd me and promptly suicided within a week of our ceremony), well, maybe we need to examine ourselves to see WHY we need that so badly, and then seek help from our Family, especially our fellow sisters who likely know what we're going thru. We can't blame the Ubar, or anyone else, if we fall too fast and assume something that wasn't there. We need to accept responsibility for our own decisions. Afterall, you know what they say about assume... it makes an ass out of u and me.
