Being Stashed is the coined term apparently and it is not nice.

Hello Community,

I have a stressing relationship situation concerning me and my SO (Significant Other). Together 4+ years, we got back together within a month of separating and my SO will not tell their family or friends we have reconciled. Every-time the issue is raised I am broken up with. I have been open with my family about us and my SO interacts with my family regularly. But it puts pressures on us and the relationship. (Not being able to call until late, or pop in, date nights, family gatherings, parties etc) as it all has to be worked around my SO family not finding out. I have suggested whatever the concern is that we simply be open and honest as it gives us the best chance and removes unnecessary stress.

I have been advised that the stylish term for this from friends is called stashing and its not nice.

Any thoughts would be appreciated.
