How do i get over my distrust of women?

due to previous bad experiences of distrust i have faced in previous relationships, i now find it difficult to start new relationships and in some cases find it difficult to trust any femlaes in general because i cant figure out whether they like me because of the person i am, or because they see me as an easy target for someone to maniplulate. as a result i find myself sometimes being abrasive, y or a complete idiot because i always think the worst. can anyone help me get over this?
