Should I want to do this? yes or no or comments...Pls help?

should i want to forgive & trust my ex gf/fiancee again after she hurt and broke my heart & couldnt be honest about her feelings with me. i want to but at the same time I dont want to go through the pain and heartache again. i truly love this female, and also she dont want to face me and talk to me, she did everythig via phone and text without talking to me face to face. im not forcing her and dont want to, i just think i beleive i deserve respect and to know why i got hurt. do you think if a person really loves you, they would want to talk and work things out. but she gets angry and defensive. should i just move on and stop it with her?
