My grandparents are the people that basically was in my entire life they live down the street so when i was younger they where like our baby sitters and 2d parents if anything was to ever happen. They are old but i'm unsure how accepting their religion is catholic but i don't think they'd drop me in the trash if they found out i just don't know if they would agree or disagree. I have only told my parents and my aunt and uncle the rest are probably still assuming I'm bisexual. I feel like i do and don't want to tell my grandparents and the only reason why i suddenly feel the need to say something is because whenever we go out to eat dinner at a restaurant or try to try speak with me they ask if i have a boyfriend, and i say no and try to move past the topic of men. This does continue to happen though and i don't want them to be shocked one day when they find out i'm with a female that's just not what i would want to put someone else in the situation of so i find telling sort of needed. Yet, i came out in such a confusing and unplanned manner to my parents i don't want to do that to my grandparents! any help? and should i tell?
If you're not sure of their views on sexuality, you could try bringing up a LGBT current event and seeing what they say. Perhaps the Supreme Court ruling on marriage? It sounds like you are very close with your grandparents. Do your parents perhaps have a better idea of your grandparents' opinions?
My parents, I really don't want to get them involved in this because of a mixture of reasons not all bad not all good. But I can surely ask my aunt, you have a good idea.
