I love two. No problem.
No one-I repeat NO ONE-including the two loves of my life can promise ANYONE including each other that I will be anything. Only I can do that.
Likewise-you can't promise anyone that another person will be anything. Not your right, not your place.
THAT is the line of reasoning that is arrogant & the same line of thought generally leads only to disaster.
If drinking ignites more open behavior from people who sober aren't ok with it, and this is ruining friendships, how about taking alcohol out of the equation? If they aren't interested sober, they aren't interested and you can avoid the drama.
