I thought I was on my page, but it was actually hers. This caught me really off guard and I don't even know how to approach it.

There was a conversation between her and this guy....He asked about what she did last night.

She said she stayed in with some friends, watched a movie...then went to bed. (She was with me, watching a movie, then left at 10PM...)

What bothers me about this is there is 1 of 2 possibilities here:

1. She didn't go home when she left my house like she told me...so she basically lied to me.

2. She doesn't want this guy to think she has a boyfriend.....

I'm pretty upset, but I don't know how to approach this....Should I bet upset? Honestly I'm pissed. Either outcome with this is total bullshit.
