If you think about it, we’re all 9 months older than we think. In the US we start age at the day you were born, not conceived…. Also, as someone who is 33. There is no difference between 18 and 19 in terms of “maturity.” Both are equally young and immature. If it works out, when you’re 33 she will be 29. Not so weird on the grand scale of life. Or at all really.
Yeah I gotcha. I think it is fine for you to date her if you like her and you shouldn’t worry too much about the age gap, but also understand if it’s your reason for breaking things off if it feels too weird to you. Tbh I think it’s kinda in the gray area where you just need to make a choice that you can defend ya know
