What to do?!?

I met a girl in my cousin's party. She was really hot HB9. We got along well during the party and exchange numbers. We go out at bars, dance and have some drink. All is well, as far as I know. Then one day, I was surprised when she went over to my cousin's house and she seemed cold to me. I don't really know what happened or did I make any actions that might offended her. I really don't know. I told my cousin about this and she told me that she was really interested about me but had some kind of a blockage since I am the cousin of her bestfriend. I really don't know what to do in this situation guys. I don't wanna mess up this time.

To over come this issue you have to first illicit her to tell you about the problem. I would say "Hey cutie, you've been quiet lately, what's up?"

She probably wouldn't tell you right off the bat so you're going to have to do some fishing to bring up that topic and demonstrate that this isn't an issue at all.

Perhaps you can engage her into some activities with your cousin so that she will feel it is ok for you guys to hang out and be together with your cousin around.

Let her reflect on the situation. Try to let her see what's happening between the two of you. You can say " Hi, you seemed so aloof lately. We'll that's what I've observed. I want you to know that I love hanging out with you." Also, try to convey to her that it's ok to hook up with you even if your her bestfriend's cousin.

It could be an awkward situation for her since you are her bestfriend's cousin. Try to make her comfortable with your cousin around. Just let her enjoy the moment hanging out with you or your cousin. Then, find a moment where you can Isolate her from your cousin and express yourself to her.

An update to my story:

Everytime we hang out with my cousin and her, I always make her enjoy the company. I do myself to make her comfortable and I usually make her laugh with my jokes and gestures. That's typically my personality. I had the chance to have a time alone with her in a beach and had a stroll along the shore one afternoon as the sun comes down(quite a romantic scene). I told her how I feel about her and she told me her awkward feelings about me(because I am her bestfriend's cousin). I told her it is okay and my cousin would not give a bog deal about it. She lightens up and we made out a couple of times. Quite a sweet and romantic ending...

Good luck bro. For all three of you, I hope this turns into a fairytale romance.... or that you guys at least break up amicably enough that there won't be any weirdness after. I usually steer clear of hot girls related to my chums because I like having friends. Although most guys seem to weather this better than girl friends, I still hate weirdness about hanging out at a friend's house. I like free food so much to alienate their families. Haha.

Thanks guys!

Congrats dude!!!
