Search Results: ex wants to be close with my new friend

Okay, so me and my ex in a nutshell. We dated awhile back for a good while, nearly ayear. She left me for no reason. She came back once ihad a new gf, abd ileft my new girl to go back to her. Ileft her afew months after, in need of helping myself. Igot depressed with my job and felt iwasn't making her happy. I apologized mid summer cuz I love her and figure she deserves that much., and she told me she no longer loved me, and she loved her new bf who was a former ex. 3months later she hits me up and we start hanging out again while she still w other guy. She eventually told me she loved me and I was the closest person she'd ever had, but she wasn't ready to let go of her bf. We stop talking again. 3 More months later, she hits me up again, she adds me back on social media. A few days after we're communicating again, her and her bf break up over something bad (Idk details). Seeing this opportunity, i ask her out to watch the super bowl with me (3days after the break up). She said she didn't want to lead me on by doing that tho... What?

It looked to me like iwas a safety backup plan, and sadly iwas going to take it. It was my fault iI left her after all. Iwas ready to count My ducks and give it another go.

All advice/opinion are welcome. Whether or not I go after her is TBD. I'm disappointed abd hurt, but more than that, plain old confused. Knowing our past, why hmu and try to be friends? Isn't that in itself leading me on? what do y'all think? Or at least, what does this even mean? How did i go from top contender, to irrelevant in3 months?
