An incel is not someone who doesn’t want to date single mothers or who’s been in a relationship for nine years. I don’t think anyone would call you an incel. Incels are known for picking the wrong women because many only show interest in women who are “out their league.” Still they’re not really “picking” these women because they don’t have relationships with them. They simply lust after them.
However it’s not even that. They are single because they hate women and have personality deficits.
