Hi, I've never posted but I lurk on a pretty regular basis.
I've found myself in an interesting situation with another girl and I'm not sure what to do about it.
Are you ready for a monster of a post?
Some back story: I just graduated from college and the friends I made there were VERY supportive of my body type (I barely fill out a 32A cup, and the rest of me is on the line between skinny and pear-shaped. I like my butt, sort of). I was spoiled by them, for sure. They always made me feel beautiful. Now I'm in a new place with new people, and the girl I get along with the best has a nasty habit of putting me down. I know, I know, how can I say that we get along then? Well, everyone else is worse, believe me.
But back to this girl . . . I think she may have self-esteem issues that she's taking out on me. She's a dominant female, for sure, and what she says to me is always delivered in a slightly aggressive, mean tone. She'll say things like "you don't need a bra, you have no breasts" (I don’t wear bras, btw, and if I have to it’s only to hide my nipples during professional events) and so on and so forth. It happens over and over again. Not only does she point out my lack of a chest, this girl goes out of her way to point out her big tits CONSTANTLY when I'm around, and even worse, when other people are around too. I won't rehash everything she's said; just suffice to say I'm sick of it.
I've been dealing with low self-esteem for a long time and I don't need her negativity bringing me down, but we are forced to live in super close proximity for the next few months. How do I tell her to quit it? I’ve never had a girl try so hard to bring me down before

.
Luckily for me this story has some happy moments. I have two occasions to relate, but first I will be referring to myself as S, the mean girl as N, and the hero of the day as E.
Like I mentioned, N pointed out my body shape on more than one social occasion, and on two of these E (a boy) stood up for me!!! Who would have thought, right? Anyways, I can’t figure out how to say this without saying it all so here goes:
I'm good friends with an Australian guy - from here on A - and I was asking him what he thought about Australia banning small breasts and squirting (this was out of genuine curiousity - and we're a pretty open group.) So we’re talking about this and I'm feeling pretty good about myself regardless because I'm drunk, and E comes in and asks what we're talking about. I was listening to A and didn't answer. N fills him in, and then apropos of NOTHING she says "yeah, S is flat and she wouldn't be allowed to do porn in Australia . . ." I sort of shout, "hey, what????" in total disbelief. If we were having a conversation about modeling would I say to someone "oh yeah, we're talking about modeling because N could never be a model . . ." NO!!!!! WTF? She couldn’t, by the way. Anyways, E looks at me and asks “what’s wrong with your breasts?”, tells me I'm sexy, then calls me "sweet tits." Seriously. I almost died laughing.
Another time N was yet again talking about her AND her mother's enormous breasts (some ridiculous story about how they put deodorant under there). So I'm drunk again (I swear I'm not an alcoholic) and I look down at my chest and say under my breath "no need to worry about that." One girl started cracking up, then E looks at me, puts both thumbs up and goes, "hell yeah"

!!!!!!!!!! The best part was that N got super defensive and tried to defend big titties to this room of people who were clearly on my side (the girl cracking up has a problem with N too, I think she understands my frustration with her blatant power plays).
The best, best part is that I know N has a mini-crush on E, but he's totally into me. AND he's German, so he comes from the land of titty and still thinks I'm hot. AND he's sexy.
Ladies, there are men out there who want your little titties, no matter your body type.
Anyways, he’s gone now

, hence my current problem of continuing to deal with this girl. Any advice? Sorry for such a long, mostly incoherent post; sometimes I just need a wild vent.
