heartbeats and staying true

so, last night, my boyfriend's ex girl sent me a message of FB. she basically told me that he's a jerkface, asshat, douche bag and everything that comes out of his mouth is a lie.
um.... duh? aren't all men like that? the thing that pisses me off the most about this chick is that she's behaving like a sore loser. not to mention the face that she asked him for a relationship, but she said that he said no and that he needed to work through some stuff. yes, sweetie, that was the guy's nice way of saying "i'm just not that in to you". get over it. so what if he started dating me a little bit after that? he obviously made a choice, and it wasn't you. grow up. put your big girl panties on and deal with it. i mean, if he's so bad, then wouldn't his family have mentioned that when i met all of them at New Years? wouldn't his army buddies tell me something? would he have given me a key to his apartment if he was going to be a huge jerkoff? i don't think so.
then she messaged me again this morning, telling me that he broke her heart, that she didn't want me to end up like her and that i probably don't even know about her. no shit. men and women get their hearts broken all the time. plus, all i have to know is that she's an ex. end of story. what else do i need to know?!?! crazy women like this make the rest of us women look so so bad.
I haven't written her back, although I dearly want to. Just to say "he and I are happy. I'm sorry he chose me over you, but he made the better choice. stop acting like we were competeing for him. I didn't even know you existed until now, and now I just think you are still in love with the guy who tried to, gently, let you down. You're the ex, that's all I need to know. I don't want to know anything else. If this relationship is going to go up in flames, then that's on me and him, and has nothing to do with you and your so-called warnings. Act like a real woman and move on. don't bring your bad shit into someone else's relationship. Now back off."
But I won't. because I am the better woman. Because crazy ex's never accomplish anything other than making themselves look like desperate idiots. and because she doesn't need any help being crazy. I've told the boy about this, just to let him know, and i just personally hope that she goes away soon!
