Should I keep trying to get back with my ex?

Well I broke up with her I couldn't deal with the way she treated me & she kept acusing me of things she never told me about but said I've done she kept playing with our relationship like a game "i don't know I heard or I figured out this maybe I'll stay with you" yet I've done all I can to be there for her to treat her with respect & care & I gave her space & I was as she said the best boyfriend shed ever had but idk why she said she was upset I was "perfect" how I never cheated or did anything wrong etc yet she almost made it seem as of she wanted to break up with me so I had enough I ended it she made it seem like I was the bad guy I tried to be friends with her now we talk but she made it seem like she never did nothing wrong when thanks to fb & friends I've caught her ignoring me flirting with others so i said friends cus we've been through a lot but I don't talk to her unless she does & we worked things out but she talks to me & acts like she never did nothing that's what grinds my gears I deserve at least one apology but she flirts with me & tells me she misses me & doesn't wanna have our relationship end & that gets my hopes up that oh ok she changed but again she flirts even worse now that she's single & she allways either ignors me when we talk or says she has to either sleep or take a bath & I catch her either talking with other guys or ignoring me so I'm like am I her toy to talk to kill time until her fun starts idk what to do even being her friend is to much but I really care for her after all we've been through & she lies about not getting wasted weekends but it's a lie to every weekend she gets wasted I don't even bother on Friday-Sundays any more cus no matter what I do or how humble I am I get no respect for as her bf she said her friwnsa matter more but so far guess I don't now we're friends idk what to do
