What to do people ..what to do?

I ve been trying and trying ,showing her understanding,caring..and respect! ive tried almost everything under the sun,ive come across stern candid..straight forward.it seems within a two month period,give or take a week or two..she avoids me for a period of time.i ask her how she is doing and what shes being up to,but with her it seems to be a bother having someone interested in her/me.she is so set in her ways,she believes everything turns out to be negative,all relationships,i gave her examples of other couples and said why are they still together,its a number of things,she accused me of reading her text(somehow).she accused me of not liking her family?she doesnt walk around anymore(cause of me,i found that strange)she takes off unannouced for the weekend,and expects me to understand ?i told her i was worried,you could of told me,then i would ve been ok,she replied" do i have to tell you everything"she called it off one day,back in dec,next day she wanted to talk saying sorryconfused

now i ve been trying to find out and understand whats going on now? is this ..similiar..to someone being in abusive relationship proir to another,the this time i do things different?in a amazement we've been together for a year now..again ..is this i got to make him the ****** before he hurts me thing? is this why is he still with me ?another thing i dont fully understand is ...why she dont or didnt wanna spend time together yesterday on our one year..she made other plans while we had plans of being together..she spent it with her friend,...is this a sign of mistrust..is something scaring her,..she is such a wonderful person,her family life aint all that great,her mom a drunk,her brother in and outta jail..her other bro's break up back together..does she believe that ,thats the way life is...does she not see the light..ive taken all this in stride showed my support..but it seems that almost that i am all to blame for all that goes on around her ???????

She probably thinks true love is hopeless and doesn't trust anyone with her heart. Urge her to get some counseling before she pushes you away for good. You can't keep this type of relationship up forever. You both deserve more. Go to counseling with her if you can. She needs to learn how to trust someone and give her heart to you.
