Ex girlfriend called last night but didn't answer say anything...

Me and my ex girlfriend of 2 years haven't spoke in a little over a month. Last night I was at a party, and she calls my phone. I pick up and say Hello twice and there was no answer, so I hung up. I just heard background noise that sounded like she was at a party as well. I highly doubt her pocket dialed me because she's never pocket dialed anyone, she has a touch screen, and your pocket usually dials the last person you called, or someone on your recent calls list. Doubt it would go into contacts and land on my name of all names...

Anyway, why do you think she did this?

I once dialed an ex and put party sounds in the background. It was to make him jealous and think I was having fun without him. This could maybe be it?

Yeah I was thinking it might have been that.

Well I have a touch screen phone and mine will often call people I don't want to call and accidently. It seems to have a mind of it's own :|

But if she had called, perhaps she just lost her nerve to speak.
