My girlfriend and I was in my room and i turned on some romantic music for us to dance together with. I whisper in her ears and said I love her. She said "I love you too." I was like tell me the truth, are you serious with me? Then she said..."For sure i'm not kidding around. But..." then I finished it off with..."but you're not real serious with me?" What does that suppose to mean?

Why don't you ask her. I don't understand it either, might be because it doesn't sound technically correct.

Hm. Maybe it wasn't the best thing to finish her sentence?
Sorry to "should" on you..
I think you should ask her, as well.

Just ask her what she was going to say after
her you had finished her sentence for her.

agreed, Wait till people are finished talking for you to start.

Maybe she was caught up in the moment. Or maybe she really does love you and wants to be serious now. Either way, you need to have a talk. Tell her that you're sorry for interrupting and ask her what she was going to say.

The message is unclear. Just look for further signs, but don't look into this one thing too much. It's probably not as negative as you think it is. Don't get too worked up/worried about it.

i agree with everyone. ask her what she wanted to say before you interrupted her
talk to her

i think she ment that shes serious with you but she doesnt think your serious with her

Ask her..that seems really romantic btw.

I wouldn't have finished her sentence if i were you.
Only way to figure it out is by asking and talking to her about it..
and listen instead of finishing her sentences..
