I am known to almost all of M's friends. The ones who don't know me, it isn't because I am a secret, but because we haven't been dating long (just under 3 months) and he hasn't had the opportunity to introduce me. I am a secret to his mother and to his in-laws. This doesn't bother me. His son knows who I am.
M is known to almost all of my friends, and to my children. My inlaws and my parents don't know I am poly, so we are similar in that way. I have struggled with the idea of letting my parents know, but in the end I keep coming back to the fact that they probably will not be accepting and there will be drama with no point to it, so I stay silent.
