I like this one girl we are meeting about 2 weeks, we haven't talked about that we are couple, but we like each other and so on. The problem is that she likes do go out with her girls to party, and I am very nervous about that, I sit at home or at work and think about her all the time, some stupid thoughts come in my mind, and I fell really upset. What should I do to overcome these feeling?

Is it any all girls party? If not maybe tag along or have a party of your own and invite her. If she really likes you she won't date someone else to. Or just simply come out and ask her to be your girlfriend if you guys don't consider you 2 to be a couple.

How old are you? How well do you know her?

Though she might seem like a great girl after 2 weeks, maybe her lifestyle is not compatible with yours. Feelings aren't always enough, compatibility is also just as important.

When you have those thoughts get up, and do something that requires you to focus.

Its way to soon to be insecure over what a stranger does with her time to enjoy herself. Maybe you should be doing more to enjoy yourself when she is not around. Why should she stop doing her thing that she enjoys, because you met each other?
