they do, but there's only so much dissimulation one can do. the wounded disliked male is typically genuinely wounded and disliked, and has already internalized this and developed chronic low self esteem, leading to distrusting or resenting any woman interested in them and lashing out, or assigning her lower value (for being interested in such a lowly creature), or doing a 360 and believing he's now hot shit and cheating on her, or feeling like it's now his only chance to have the upper hand to hurt someone else, etc
some do all of the above to different women and learn to play up the woe is me act to lure in even more women
if you're letting moids hijack your nurturing instinct, you have to learn to pick out the ones without the internalized inferiority, which is very difficult. better take your chances with Chad.
