What should i do??

So i am doing now 90 day No PMO, and Maybe more days challenge. As some of you might have seen i posted a thread about benefits after 55 days of no PMO.
I mentioned there one of my Friends. She is working with me together as a lifeguard in smth like Coast guard. I know Her since i was 12 and she was 15. As a young child i fell in love in her, but You know how it is with holiday feelings . I was only a good friend for her during this holiday damp. When it finished we have lost contact for about 7 years. We meet again at my current job. So back then in 2015 after reuonion we were just friends. I had no expectations and etc. When i had problems with girls or family she was by my side. Meanwhile she dated other guys, but never talked about them to me. When i started my transformation we somehow got closer. She invates me to parties at her flat, she wants to go with me to dance clubs, and once when we were she got very drunk. She was touching, huging me and it looked like she want to kiss me. I Dont know now, but month ago i was preety sure she did it. Ofc i refused couse at that night that was so strange for me! She was my friend! But from this day something had changed. When i made a party i invated my best friends from whole Poland(students, seafarers).
My best friend from high school is kinda a playboy. He can pick up all grils and know their body language very well. He told me that he observed us when we were talking. She was constatly closing gap between us, and was intrested all the time when i was talking while she wasnt intrested at all when she was talking with the others. He also said smth like she is probably afraid to try due to age difreance.

I just Dont know what to do. She is Indeed beautyfull soul and women. She has a lot of intresting passions and hobbys. We both are dancers, lifeguards...
Couse i Dont want to lose her as a friend, but beeing with such Amazing women is so worth it :/

Your opinion guys? How should i clarify this situation?
And God bless You all here!
