afraid of what boys could do

i was in an abusive relationship for two years and it ended last year, but i feel like ever since him i’m just so scared of what boys could do to me. i hate going out to boys unless i have a friend with me and if i could i cancel on them. one time he was like come on inside with me and i was thinking about what if he touched me and i felt so uncomfortable and tonight i was with my friend and he punched me (mess fight) and i punched him back saying dont touch me because it reminded me of him
