I'll try to make this as short as possible, so here's the deal:

Me and a really good (girl) friend, who I have never gamed(until earlier today), were hanging out with 2 other guys, and i kinda realized that i'd be down to get with her, and so i started gaming her to see where it goes. and tbh I think i kinda like her now, she may be one of those girls, you know. She's i'd say about HB8 . So i started flirting and doing the usuall push and pull and c&f routines, and escelated physically several times, to the point where i could feel the sexual tension, and i could tell she could feel it too (body language), E.g. 1. She leans her head on my shoulder, while we're looking at some pictures.
2.While my arm was around her she started playing with it, and rubbing it...
(both of these happened at different times)

Now, do you think those ioi's are enough for me to escelate, and how do you think i should escelate.

Ps: We are also going to a party tomorrow together.

Yet again i don't want lose my friendsship with her, although i'm confident i could game her and seduce her...ahh im confused help me!!! Should i game this girl do you think???

Pss: Also her body language through out the whole day was suggestive...VERY suggestive

seems like she intrested in you, Have she ever told you that she considered you "we are just friends"? if not then you are good to go, go in for a kiss. Cause the last thing she could do is put you in the friend zone lol!

I'd escalate. If she rejects your advances, at best you won't really be losing her as a friend given the signs.
