<human>: Hey R_A long time no see!

I [22M] have recently gotten into odd situation with my ex [22F]. We had a year an half relationship back in high school that ended rather bad, a lot of lying and controlling issues on both our parts. We were young and rushed a lot of things but slowly got over it. We haven't "grown up" per se but more matured and understanding of who we are as individuals. 

It's been five years since we have been "close" an have agreed on having a FWB type situation.  So far so good!

Now hear in lies the problem, we're each others first loves and after hanging with her again you can tell how the chemistry has not subsided. We haven't been very physical, barley any sex, and random kisses here and there. (Which okay 10000000% with me) also a few dates here and there.

My question is that I'm getting mixed signals I'm not sure if this is a relationship type thing or purely FWB. One minute I get "I love you's" the next I get called "buddy" or "best friend" I'm definitely not ready for a relationship but what we have is a FWB that seems more relationship like.

How should i talk to her about this with out making things awkward? What if she doesn't want just FWB.   ...hell, I'm not even sure if I just want a strictly FWB thing. I'm just so torn.

Give me the gist of the text in a nutshell
<bot>: fwb with an ex after 5 years ,not sure if its leading to more than a fwb because of mixed signals. How should I talk to her about it?
