She says we're on a "break".?

Basically my girlfriend says that she needs to think and to work out what she wants, so she says we're on a break. Yet while we're on this break in the first night she talks to a guy she likes all night for 3 hours. I see her the next day casually and she tells me how she's going to drop my jumper off at my house later. I'm like "but we're on a break, don't worry about it I don't need it at the moment" and she goes "nah I want to give it back now".

She's been seeing her ex casually behind my back and she has feelings for him and he has feelings for her but he says he knows it won't work if they get back together. She also has feelings for a person she met 4 days ago. He says he doesn't like her back though.
So I don't know who she was on the phone with all night but she wouldn't tell me who it was.

She says I'm too clingy and she just needs space and to think. But I'm afraid that if we're on a break and she talks to other guys that she likes then she will end up losing more interest

Break up with her. She's using it as an excuse to be a slut.

Wow. You should break up with her while you still have some dignity. If I was in your shoes, I would. What she's doing is crazy. It's cheating. "Break" my a$$. It's just an excuse to see other guys before getting tired and going back to you. Break up with her and tell her it's because you found someone else. No offense but she sounds like a whore.

break up with her. its her easiest way to let u down without making it all hit at once...u wont get back toghere esp if she thinks your clingy..i was hella clingy with my ex and he was a cheater and yeaa it didnt work out...were still good friends tho.

Im sorry...its over.
