Wow.. ex's? really?

So my ex is one of my friends, but the thing is, I use to buy her things.
yes her, I dated a girl once. It didn't work out so well.
So anyways,
She has a boyfriend, which is cool, I don't really care about that. she wears and uses all of the gifts I give her. I mean cool, yeah your using the stuff I bought you, that makes me happy....I guess. At least the stuff is put to use. I just hope its not awkward with her boyfriend you know? but you know the best part?... She gives her boyfriend the gifts I bought her, and has him wear them.Has him use them.
WTF?
 Common sense? really? you got to be kidding me..
Thats all I got to say.
thats just stupid.
Its kind of like:
Girl: Hey, you can wear this, my ex bought it just for me ^_^
Boy: Great, I'll take care of it and wear it.
Girl: Great! :D It's mine now so it doesn't matter.

Um...... really?
wow...
