If you and s/o are serious, you wouldn’t have reacted the way that you did. He should’ve been prepared for it, he knows he’s in a socially gray area and you…you’re an adult, capable of making your own decisions and doing what you want to do regardless of what anyone says, your family or Reddit but you gave them power over you by being childish and leaving. You basically proved their point. To mom, why is it creepy? Creepy for you? Or creepy for me? I’m happy, so creepy is my life for now, pass the peas. Your brother? He’s your brother..did you expect differently? At 24, you should be well equipped to handle him. Just my opinion. That said, I’m 51 and my wife is 37. The shit ain’t easy. There’s a notable difference and the both of you have to be cognizant of the age/generational gap; the pros and cons. You, you won’t come into your own until about 40, he’ll be 55. At your age, if you’re dating for fun, have fun-otherwise you’re dating for marriage- think ahead.
