PARENTS 😖

Sooo I'm so worried, I'm sitting down and having a proper meal with my boyfriends parents of 8months. It's so over due but because of timing, it's never worked out. I've met his parents many times and we've had conversations and stuff but I've never had to sit down and talk to them and get questioned and stuff... And wtf do I wear 😖 what do I talk about, I've never had a serious relationship before and I'm scared!!!!! Ahhhhhh
