<human>: So I (24f) broke up with my boyfriend (34) of about 3 years about 3 weeks ago. We still live together (I'm looking for another place to live) and up until now we've just kind of stayed gone until bedtime. He would stay in his room, I would stay in mine when we were both there. Everything was going great until he brings his new girlfriend in. She's super loud and her dirty looks are not appreciated. The guy told me he'd never let anyone near his heart again and yet this happens. I realize I shouldn't be upset because I dumped him but the reason I did was because of some deep personal issues I needed to fix. So what do I do? Stay miserable until I find a place or let him know I can't handle her being there?

Can you give me a shortened version of the text?
<bot>: I live with my ex, his new girlfriend is working my last nerve and I've only met her once. But I could see this being a nightly thing. What do?
