How would you have reacted in this situation with your new bf/gf on your first vacation and whats your sign?

I have experienced the same thing. My boyfriend Libra took me out on a date to meet his "friend" Sarah. They sat there and talked and completely ignored me the whole time. He was sitting closer to her then he was to me. I remember when she first layed eyes on me her eyes got all big and she gave me a weird look. Then it seemed like she was happy to take all the attention away from me like it was her and him together or something. they were treating me like I wasn't even there. I let it go on for like 45 minutes and I kept trying to get my boyfriend attention and get involved in the conversation but he was consumed by her and she didn't seem to mind at all. I went outside after I made a bitchy comment to see if he would follow me and he didn't. I looked at them through the window and they just kept talking and laughing. I was planning to go in and make one comment and then leave in a taxi and never speak to him again. But when I said "I thought I was coming here to hang out with you guys not to watch you two hang out together" He started paying attention to me and ignoring her. By that time another friend had shown up, she was a ***** to me and completely ignored us. I guess she said she never wanted to hang out with me again cause I made her so uncomfortable. I was like she has the nerve to say that after trying to act like I didn't even exist sitting closer to my boyfriend than I was? I told him to pick because I wasn't gonna play these little games with his female friends. (It was the 3rd girl he did that to me with) He picked me over all his female friends. I will not put up with that ****. Come to find out he had slept with almost every female friend he ever had. ( I found out by going through his e-mail) If something seems not right then go with your gut.
