I'm in a relationship with the girl I've liked for a while. She'd just gotten out of a long term relationship and the first two weeks were pretty great, like a regular relationship. She broke up with me because she didn't feel like she was ready for a relationship, but soon we got back together. We've gone all the way too. We haven't had any alone time for about two weeks, and now the relationship just feels unhappy. She's a dead puppet half the time because her ex boyfriend is constantly begging for pity everywhere. Updating his Facebook statuses with songs about heartbreak 24/7 and writing about how he's been crying so much (one was a page worth's story about how he ran errands in his car and cried the entire time and others mocked him), tweeting about it too and reminiscing about how great things were and how miserable he is now. This wouldn't make me as mad as it does if she wouldn't just so easily pity him. She feels bad for him all the time and it ruins her mood, and she indirectly tweets back to his tweets (her latest one a song lyric about how she thinks of him all the time [yeah, me and her are dating]), and she writes back to the annoying pity letters he writes her. Even that I could over look, if it didn't feel like she gave up. 3 weeks ago she would go out of her way to do the sweet little things girlfriends do, now she's just totally stopped. And she knows it too. Yet, she still says she wants to be with me (though she really isn't doing anything to make me believe so) and she doesn't want to break up. Reddit, could you please explain to me what's up in both their fucked up minds, and suggest what I can do before this thing ends up eating me alive?
<bot>: Gf's ex's bitchiness is putting a giant dent on our relationship, which is further made worse by her messed up priority list which puts tweeting song lyrics about him higher up than me.
