it is interesting to me... and I've seen it in several relationships of survivor friends... as we heal and face our shit and change who we are how that upsets the dynamics in a relationship. some partners will change too and discover themselves at the same time and some won't.
what we can't do is take on the blame for what others are feeling and the dysfunction they bring in from thier own childhood.
change is scary but we also evolve as people as we age and get into differentstages of life.... so getting the " old" person back for the sake of a more workable dysfunction for the partners sake is nutty.
Muligan and I always thought about it as jumping on the train or being left at the station.
while it may make her a bit uncomfortable.... you exploring your sexuality prior to marriage should not be a game changer.
On the flip side I have a couple friends who ended marriages because thier true self was as a gay man... very tough for the spouses.
communication is the key ... work together and figure out what you both need while maintaining healthy boundries. try not to backpack fight... doesn't help. Focus on the issue at hand.
