I was close to my family, had left for twelve months and they began guessing that my friend was actually my boyfriend. I wouldn’t confirm and we had a few months where they seemed to live with that and then they suddenly felt guilty and decided to tell on me. They now shun me even though I’m not dfed. It’s been 16yrs.
Your partner may find it difficult to comprehend the consequences of their request, they could do some research and find out. But it’s your life, not theirs.
I sacrificed my family relationship for freedom, not for one person because losing your family could make you come resent that person if things get tough. Feel free to DM me.
