So I was in a club approached a chick HB7 then out of nowhere comes a very bulky dude and talks to her and tries to cut me off her. I asked him what do you want from me she is not your girlfriend. He then starts to provoke a fight with me and I back off because I dont want to fight over a pussy. Little bit later she comes to me, dude is nowhere to be found, and starts showing interest. I escalate and we make out a lot but we don't talk too much probably because I was drunk. She then starts to go to toilet for long periods like 10-15 minutes, probably messaging her girlfriend how she is bored and want to go somewhere else I dont know. When she comes back she is still all over me though and we make out a lot. I asked her hey lets go to my place she said "No Im with friends". Then she starts to say to me"I know you have a girlfriend". I say no I dont. She continues to say"No, you have a girlfriend" and I continue to say that I don't. Its 5 oclock so the club is closing and we have to get out. I said lets go to my place but she still refuse. Then suddenly we meet this bulky dude from before and she starts talking to him. I said to her come with me but she continues with her stupid"No you have a girlfriend". I said ok and she walks away with the dude and I walk away. So what could I do in this situation to make her go with me? What mistakes did I do? Strong critic would be appreciated.
