I was with my ex girlfriend for 18months, and we broke up about 4 months ago. We both attend the same 6 form and are very very close. We both consider each other best friends.
Since we broke up, she had a relationship with a guy at 6 form, but didn't work out, mainly because he didn't like the closeness of her friendship with her ex, me.
However she only broke up with him a week ago. And last wednesday we were talking and I suggested we go to the cinema on friday with a few other friends, however she said no, saying she was busy as she had a family night in planned with her parents. I thought at the time this was very weird as they never do anything together on fridays nights. However I left it at that.
However I decided to ask her again on msn what she was "really" doing on friday and she said the same as before. I even asked her face to face if she was meeting this lad she had said something about while with the other lad in 6 form, and she got quite angry with me that I didn't believe her, So In the end up actually belived her.
Then on saturday morning she text me telling me saying that she actually went on a date with this lad on friday and didn't tell me because she didn't want anyone to know.
Now, I am angry at this because of the blatent lies she said 2 me, and feel hurt by this. And I am not talking to her now since saturday morning, she has appolgised by text but still.
Am I being unreasonable?
