All my cousins are female, so I never interact with them / don't even have their numbers (which proves how fuck'd my family life is - as I have no more family members, since my mom / dad are both dead). The last time I saw any of them was at my mom's funeral and they couldn't give two fucks. The only thing they ever said to me was utter "sorry for your loss" and that's that... all the while they have their shit together, have boyfriends (or married), love in different parts of the country (USA) and are living happily ever after.
Cutting ties with family is probably the best bet you can take as an incel. Not worth having mogging sex-havers constantly remind you how bad off you really are.
