Best of luck! I "came out" to my mom last year (partly because we have a negative history, so I get perverse joy out of telling her things that I know will drive her crazy now that she can't do anything about how I live my life), and she still doesn't quite get it. I came out to my dad just a couple weeks ago, and he didn't seem too pleased, but the only concern he voiced was whether Hubby and my kids knew. (He wanted to make sure Hubby did know; he wanted to make sure the kids *didn't*. Though my older one does.)
Me: 44, cis-het female, poly
Hubby: my husband, 42, monogamous
S2: my "attachment", male, 44, undetermined
Best Friend: male, 38, platonic; the one who keeps me sane through all this!
My daughters: Alt (age 19) and Country (age 16)
S2's sons: Spikes (age 9) and Beads (age 6)
