Help with ex girlfriend please?

to make a long story short...shes 23 im 20. we lived together 6 months dated one year. kept fighting so i got mad and broke up with her. got back together a week after then she broke up with me because she says she cant deal with the heartache and hurt i caused. we been talking for about a month and a half via text message and calling. last week she said we should stop talking altogether and see how we feel. everyday i still get a text from her saying i just wanted to say hi, i miss u, goodnight, i hope you are doing well..and things like that. do i just ignore these or write back? whenever i suggest getting back together she just says she doesnt know shes just not ready yet. should i ignore all messages and calls from her?
