Can i get good advice please?

ok so me and my ex broke up 2 months ago. she was completely horrible to me when we were going out. she called me another guy name in bed and insulted my mam on accasions! anyways when we broke up a week after we were both out and she got with a guy right in front of me..... i was gutted because at the time i did love her but the following i texted her to say no-one will ever treat me the way she did and that she'll never hear from me again!!!!! last month i got a text from her saying ' glad your friends ignore me when out, after 3 years !!!! ' i was so tempted to write back saying ' you couldnt even get my name right in bed after 3 years ' but i stuck to my word and didnt text back. 2 days ago i got a text from her saying ' hey..... just moved home this week and was tidying my room when i came across your hoody, what do you want me to do with it ' i didnt text back to this either. what do you think shes at and do you think i should reply or remain silent????? thanks guys
