He loves to play mind games, please read on.!!?

me and my ex faced loadsa problems, so im not sure if i wana be with him just yet, as a cuple, as iv gon through so much pain due to his actions before, he sed he wants to know if we can be together or not, and when i said that to him on phone, he said then i have no time for you, and i dont want to be with you, and hung up on me and when i called back loadsa time dint pick up, a few days later i recieved an txt sayin "i miss you baby" so i txt him the next day and i sed im changin my num and thot i shud let you know and he said "ok" thats all, and when i txt him recently asking him about something hes doing, he started getting funni, and swearing at my mother, saying he f***ked her n that, just like her daughter" (me, although iv been with him for the past 5years) and simply want bothered if i exist anymore. im sick of his mind games and dont know what he wants, everytime iv planned to move on, he comes rite back in to my life and starts playing his stupid mindgames, so now iv decided im never gona speak to him again, for disrespecting me and talkin like that about my mother, but then again he always does as he pleases, and would only talk to me when he wants to, im so sik of it, and dont think i can get over him, do u think iv done good by calling it quits between us?
