Lost my scorpio...??

Hi All. I was in a strong loving relationship with my ex scorpio for 2.5 years. I left for 18 months overseas and we didn't spend any physical time together. we decided to put our relationship on hold until i got back and see other people. We kept in contact through phone calls and emails, everyday the whole time I was gone. I return home and find out at that moment, she started dating an ex-boyfriend before me 4 months ago and never told me. She told me previously she wasn't in love with him years ago, but now all of a sudden she's in love with the guy and she has zero physical affection for me and wants to be friends, even though she complimented my body and asked me to stay buff like I am. I told her good bye that night and I was hurt and she hugged me. She slowly started texting me and calling me, I was thinking it was because maybe 'out of sight, out of mind' and she realized I was back.

so fast forwarding 3 weeks, I asked her to have coffee and talk because I had time to process all the emotions I had and still cared about her. She said she would feel awkward and that she thinks she's in love with this guy. Mind you she reaches out to me and sends me pictures and flirts. Now I feel like I am being played. She says she doesn't romantically love me anymore, but why keep in contact the whole 18 months like clock-work? She proceeded to harshly speak to me on the phone telling me just enjoy the 2 1/2 years we had, its not like she was the best love of my life, and enjoy our friendship. I don't want a friendship with a woman I was in love with and could possibly still be. the 18 months was hard, but I remembered the time we shared together.

I decided to cut her off today after she basically called me a good 'snippet in time'. Do you think she will try to come back around?

also she told me to pretend like she didn't exist anymore, BUT if I ever need anything she will be there for me no matter what. its so confusing Its been bothering my Sagittarius brain... and the guy is a LEO so its not like compatibility wise we are much different. We talked about marrying and having kids before I left, now I feel like I'm just some guy in her past that she's just being friendly to because she knows I'm a great guy.

also I'm a scorpio rising, so I think it helps balance out my Sag Sun, Aries Moon, once I find someone I click with I am loyal and loving 1000% , I completely stop flirting when it gets serious... but now, I'm starting to feel betrayed and that's never good because my deep scorpio anger kicks in.... my superficial fire anger is just yelling and moving on, but that's not the kind I am feeling right now.
