I am the hinge between Murf who is mono and Butch who is polyflexible. Who is without another partner by choice.
There is no way I would allow Butch to dictate what kind of relationship Murf can have with me. How dare he feel like he has that power. Your gf needs to set boundaries with her husband. I have done overnights with Murf from the get go. We spend every other weekend from Friday to Monday with him, and a night or two during the week too.
If nothing were to change are you going to be happy.
40 yo straight female
Married in the eyes of the government to Butch since 2001...
Murf my monogamous second husband has been with me since May of 2012.
In a V relationship with an average 50/50 split of time between my two husbands.
