<human>: A little background: I've known "S" since the 1st grade and we've been best friends for as long as I can remember. There has always been a ton of chemistry between us, to the point that multiple people have told us individually that we should date. However timing has never been on our side. We've both been in serious relationships since HS with different people and were never single at the same time.

Last year my ex-gf and I of 3 yrs broke up and I told "S" everything, as she has always been my best friend. This past January, "S" and her longterm bf broke up. 

A couple weeks ago, "S" and I went as each other's dates to a mutual friends wedding, and ended up getting drunk and hooking up all weekend. 

It's happened a couple more times since then when we were sober so I know it wasn't some drunken mistake.

She's told me a few times that she's not ready for a relationship and wants to enjoy being single for a while and get to date around for the first time in years. 

My problem is that I genuinely have feelings for this girl and even though she says she doesn't want a relationship, every time we're together she acts like my gf (rubbing my leg under the table, cuddling, etc), yet she actively keeps reiterating that this needs to stop because it could get messy and then 2hrs later is all over me..

I'm just frustrated because I don't know whether or not to keep the whole thing going in the chance that she decides she wants to date or if I should quit the physical part and just go back to being friends so I don't get fucked over.....

Can you condense the text into three sentences or less?
<bot>: I've been FWB with my best friend and I caught the feelings and even tho she says it's not mutual, her actions say otherwise and I have no fucking clue what to do
