relationship

If i am true to her and she things , i will first compile mys self and think what action made her to think i this way ? I will rectify if i have made mistake. and ask her for the discussion to subtract our diff.. Thats the way to solve a problem ...

Either your girl friend is the overly-suspicious type, in which case you might be better off without her, or you have given her some reason to not trust you. Why not ask her what you have done to make her think such a think about you. If she has no real reason to think that, then I would advise you to find a new girl friend that trusts you and whom you can trust. It's no fun having a friendship where people can't trust each other.
