<human>: So here's what's been going on. I've been going out with her for two years and lately she's been clamming up more and more whenever I ask basic questions about her day, if she's up to anything this weekend, if she saw any of her friends, basic questions one would think. She doesn't really say 'nothing' just that she avoids answering questions about what she's up to outside of seeing me lately and through mutual friends on facebook I've been finding out that for the last few months she's been making plans to hang out with mutual friends and people I didn't even know she was friends with.

Now, I don't really care if she has plans outside of me. I don't honestly believe her life should revolve around me or anything crazy like that, but finding out that she's making a point to keep this stuff a secret from me sets off my paranoid alarms. It doesn't make any sense to me why someone you're in a long term relationship with would go out of her way to keep her social life a secret from you and make a point of not telling you when you ask. Am I wrong in thinking this behaviour is very unusual? I really don't know how to take this, I'm hurt she feels she needs to keep it a secret from me, but my lack of ability to ask her about her social life outside of me, especially in the light of finding out she's making plans with mutual friends while trying to keep it from me, makes me feel slightly betrayed. Am I out of line for wanting to know what's going on with her?

Give me a shortened version of the text
<bot>: GF of two years has been making plans more and more with mutual friends and strangers while making a point to keep it a secret and I don't know why.
