Unwanted Attention

Last night, my boyfriend and I went to our favorite local watering hole to watch our friend, who I call "Glitter Bug", sing karaoke. We had an absolutely amazingly fun time.

There was one point during the evening that I was sitting at the bar alone. My boyfriend and Glitter Bug went outside for some fresh air. I am comfortable at this bar so it didn't bother me to be sitting there alone. I am enjoying my drink and people watching when the bartender taps me on the shoulder and points down to the other end of the bar to a guy who then waves me to come over. I wasn't sure why he was waving me over, I thought that I knew him from somewhere or something. I sit down next to him and he offers to buy me a drink. I ask him "On what conditions?" He said that he was hoping that if he bought me a drink that I would kiss or make out with him. I laughed and said "That is not going to happen." He asked me who I was there with and I told him straight out "My boyfriend and my friend." He gets all mad and says "You were going to let me buy you a drink when you have a boyfriend!" Actually I never accepted his drink offer. I questioned it from the very beginning. Then, he gives me his phone number (which I didn't ask for) and says that when, not if, I break up with my boyfriend to give him a call. This guy was getting a little close and touched my leg when I boyfriend walked in from outside. My boyfriend came over and started talking to us and then gave me an excuse to leave that situation.

Throughout the night the guy who hit on me kept staring at me, waving to me and winking. It made me really uncomfortable. On our way out of the bar, the guy and his friend followed us out and touched me on the back. I hated it! I was very uncomfortable but didn't know what to do.

I know that it was my fault for sitting down next to the guy but I knew that I had back up if he tried anything really tricky. I am a pretty smart chick so I knew not to accept his drink unless I saw it being made by the bartender and I knew not to give him my phone number. I also knew that this guy was going to get his ass kicked it he tried anything...Glitter Bug is a 250 lb. guy, and he will kick ass if he needs to. My boyfriend is also not a small guy. I also knew two of the bartenders who would bounce this guy out of there if needed. So I knew I would be protected, and thankfully I didn't need to be. But I still wish that I slapped the guy when he touched me or screamed at him or did something to defend myself and my body more.

Am I being too overprotective of myself? Also, I don't want my boyfriend to think that I sought out this guy or think that I wanted his phone number. What should I have done in this situation?

(And why is it that guys always hit on you once you are taken but never when you are available?)
