My boyfriend is significantly older than me, but he looks a lot younger than he is, so I've lied to my family about his age and they have seemed to bought it. The "half your age plus 6" rule wouldn't work for us. But romantically we get along better than my last boyfriend who was ENFP and only 2 years younger than me. So I say fuck the system. And really something that my my boyfriend mentioned once that makes a lot of since is that if people knew our ages and we were both 10 years older than we are now, then no one would think twice about it. And the truth about it is someday I'll be 30 and he will be whatever age.
