Search Results: making him get excited

So, I was out at this bar and this girl I've been dating off and on 6 months now wanted to come meet me. We ve been pretty close the last few month almost like a couple and we act like a couple and spend a lot of time together. Don't know why we re not officially together and I'm rather confused about it honestly where I stand with her. But, anyhow she wanted to see me and came there. We had a drink together and it just seem something was off with her. She was excited to meet me earlier then when she met me she seemed short with me. There is about 4 different bars in the same building all connected to each other. And her girlfriends had come along with her but we re in the bar next door partying. She came to see me in the quieter area. Anyhow I asked her what the matter is and she seem irritated and says "I'm fine". So we sit there another half hour and is awkward as hell cause we just drank and didint talk. I didint talk to her cause she seemed pissed for some reason I didint know. So she says she has to goto the bathroom.

Well I sit there for 20 mins or so and she dosent come back and I become worried about her. I had to goto the bathroom too anyhow. So, I go into the next bar where the bathrooms are and see her dancing with this other guy and making out with him acting slutty as shit. I goto the bathroom, settle up, and tell the bartender to put the drink I was gonna buy her on her tab not mine. I leave and get the hell out of there, I was pissed and texted her. I send her a pissed off drunken text. She responds and says we re not technically together blah blah blah and that she was pissed at me cause I ignored her and that she wanted to have spent time with me. So, either she's playing games or I misjudged her reaction because I kindve got pissed she wanted to see me then ignored me so I ignored her. Anyhow, the whole thing pissed me off and I got heated with her big time and look lIke the bad, insecure guy now. What should I do?
