I work at a fitness center and frequently a girl comes in and we chat, I make her laugh a lot either by being strange or quick witty remarks. We play basketball she even tells me if she is going to come in the next day to shoot. She tells me who she thinks is creepy and allows me to touch her either jokingly or when showing her new exercises. She even jokes like "are you working tomorrow" yes, "ok I won't come in then." She seems comfortable around me. Is she interested or likes me?

Well I Think That You Need To Ask Her... shes The Only One That Can Tell You... I Mean If You Are Flirting With Her And She Flirts Back Then I Am Sure There Is Some Kind Of Connection There. Why Don't You Just Ask Her To Have Dinner With You Or Something!

Not dinner that's to formal ! You'll scare her off. Go for a movie and a walk... you guys can talk about what intrests you and a movie will help break the ice, don't talk about your work or working out, show your personality and that you have a life outside of your job.

Id guess yes, she's probably interested... or if not, she's at least comfortable enough around you that you should just try to explore the issue.

Just see if she takes up a casual offer... as in after you workout with her tell her you are going to grab a bite at a new place or check out a movie or whatever and ask her if she wants to go. Make it casual and just a part of the conversation. If she says she can't or doesn't want to just let it slide. Tell her you'll just tell her all about the movie or meal or whatever the next time you beat her in basketball.

I dated a girl that was in a class who acted just like you described. On the way out one day I said I was going to a coffee shop where I knew this guy was going to play acoustic guitar and would she be interested in listening to some music, cause this guy is really good. She did. We ended up dating.

So no big production. Slip into the conversation some simple suggestion. See if she pursues it. If you have some guys you hang with you can always play the I'm going with some guys to whatever, if you and your friends want to hang setup. Again, you need to make sure your friends aren't going to be stupid, but I did this also with another girl I dated. Had some friends who were going to the beach and I called up a girl I thought might like me and told her we were going out and looking for other people to join. She did with a couple of friends and again, I ended up dating the girl.

So be confident, whether she accepts or not, and be lighthearted about the whole deal. Its no big deal. Even if she doesn't accept, she still might later. I had three different girls turn me down initially just to come back later and show interest. One I dated, one I would have if I wasn't already dating, and one I decided probably was better left alone.

And then again sometimes you crash and burn. Certainly had my share of those too. But what's the fun of not taking some risks now and then? Better to hear "no" and move on than to wonder three years later, eh?

I would yes too.
She seemed interested all right if u tell me ;)

You could just say to her " why dont get carry on this conversation at a bar, have a drink together ?"

Im not saying this big fancy dinner... like find out what she likes if she likes pizza... take her out for pizza... just go somewhere that you both are going to feel comfortable

Thanks guy's so far this has been great to read, she showed interest in seeing the new movie "Borat" maybe this is my chance.

Sure is pal, go for it...

What have you got to lose?.

Nothing more to add because you are on track..

Ask her to coffee or a drink quick - before you get into the friend zone.

No dinners.

No pressure.

Be prepared though if she sees some one forher not to be as fun - also if she is not interested.

Obviusly we can not see the inter action.
