An adult woman should not be so possessive of her own birthday that she begrudges her friends the chance to get married on the same day.

I do not think it is selfish to want to donate a kidney "only" to family members.

To stop challenging someone from using anti-gay language simply because they persist in using anti-gay language strikes me as a defeatist approach.

I agree that biphobia is real, but I think it's absolutely worth considering that someone who "despises" having sex with her husband - and men in general - may not be interested in men sexually.

As you feel increasingly comfortable around your friends, I think it's more than fine to share the basic details of your heroin addiction with them. If they seem receptive, you can feel free to talk about it in further detail; if they seem judgmental or uncomfortable, you can move on to other topics.

If you don't like potlucks, the solution to your problem is "don't go to potlucks," not "insist other people don't have them."

If your partner asks you if something bothers you, and something bothers you, the best thing you can do is say, "Yes, it bothers me." Otherwise you create a situation where they think everything is fine, continue with the offending behavior, while you build up a secret reservoir of resentment that will eventually come pouring out, to their shock.
