What's up with this girl?

[370]

I met this girl at a party, we kissed and were bit drunk. Then I spoke to her a month ago, she reacted quite cold. Then month later she suddenly spoke to me and was nice and talkative after she saw me at the gym. Then 3 weeks later we spoke again and she was first talkative and suddenly cold..
Can anybody tell me somethingg about this kind of attitude? What she trying? (All these conversations were on fb)

I think she might be nervous around you, talk to her face to face and see her reaction.. She might be a little embarrassed too, not for jissing you but putting herself out there or being very drunk or she just cant remember x good luck!
