I need answers from women prefarably?

We were very happy together for 5 years but i was going through a very bad time in my life and one evening went over to her house and a few things happened that evening that led me to believe she was cheeting on me . I knew better than that in the cold light of day but she could behave like such a tart at times without actually being one . Anyway I split up with her and dumped all her things round her house at 3am after splitting with her at midnightish. It was the 3rd time in 5 years we had split every time me dumping her . But my god do i miss her know she has made sure she keeps in contact with some of my friends (the once she can claim are her friends aswell ) and with my family . She seemed to get over us with real ease even her friends said that but she was besotted with me when we was together . It has been 7 months now and i still cry , i have made a lot of chanhges in my life over that time but im still working on somethings. When i txt her or ring her she is very often quiet arsey with me and tells me that her new life is wonderful yet if one of my family talk to her she tells them that her new life isnt all that grate but she will never talk to them about me . what is going on in her head ? If i chase she runs if i leave off she is always glad to her from me wen i do break and end up ringing her . But she tells me over and over i need to move on and find myself a new gf , i dont want to . What can I do? I would particulally like to hear of women on this one guys i can already predict what u will say so dont.
