Yeah I want to be straight forward. Tell her straight up that I like her I am into her and if she is too then for her to let me know and not waste time just going back and forth. I am talking about relationship wise with this girl.

I was asking if that would be a good idea or not

Be honest with her. If you point out the elephant in the room a weird thing starts to happen, that elephant will disappear.

Just like with awkward silences, just be the type of guy that points out the awkwardness. Ironically, this will make it disappear and she will feel like you are being very open and honest with her. This will in turn make her be more open and honest with you.

You clearly can’t just keep going on forever pretending you didn’t hook up with her friend. Just get it out into the open and she will more than likely respect you for saying what’s on your mind.

She knows I dated her friend and she persued on a second date with me. I just want to know if I should tell her straight up I wanna take things to another level or just slowly go along with it and see where things go.

You keep saying "go along with it" in order to see where things go. Do you know how to lead a woman to where you want her to go?

From my experience, and I can't speak for everyone else, when I used to tell girls that I wanted to pursue a LTR those were the girls I didn't have a LTR with. The ones that I actually seduced through my actions and not words were the ones that wanted to stay around and be exclusive. It isn't a slow process either. Because you are not using words to tell her what you want, she'll seek balance by communicating what she wants from you. When she says it, she'll be more eager to make it happen...emotion is now solidly invested in you.
