He does this all day - whether we're driving, watching TV, talking face to face, he continuously picks little bits of skin off his lips and sometimes until they bleed. Then there are more bits to pick it!
He doesn't care that I find it disgusting, and gets defensive if I dare to ask him not to do it!
Makes my skin crawl
AIBU and how can I convince his it's really gross for other people and he should stop!?
