Opinions?

Okay so for reference, I recently turned 18. I’m starting college in a week and I just moved to live with my dad and step mom. I’ve been a competitive dancer my whole life and have never had a boyfriend, girlfriend or anything. Not because I couldn’t, but because I simply did not have the time or energy for it. I’ve never even kissed anyone. I was raised LDS but never fully believed it and became inactive around 13/14. My Grandma sent me this text and these pictures out of nowhere last night and I thought it was really strange tbh. I understand a lot of it was probably out of love, but her saying that I would never truly be happy really rubs me the wrong way. I could just be over reacting though. But just to be clear, I’ve never planned on having sex with anyone until I’m in a committed relationship. A lot of the reason why it rubs me the wrong way is because the family members she’s referring to in the text are two of my cousins. Both had children fairly young, and neither were married. While it’s true that it didn’t turn out ideal for one of them, the other is really happy - she’s married to the father and has two happy, healthy kids. And I think it’s unfair for my grandma to assume that she isn’t truly happy just because she doesn’t have the same beliefs as my grandma. Again, maybe I’m totally overthinking this whole thing. That’s why I need some opinions. So please share them below! Thank you!

Ps: I wasn’t sure what flair to use
