A lot of young women, myself included, start getting hit on/cat called/male attention during puberty, ~ 10-13. This translates into “You are so mature for your age!” or “You developed into quite the woman now!”. They were lying to you.

I highly doubt you look like a 35 year old at 18. The only 18 year olds I’ve seen that look 20 years older than they actually are, are usually on drugs. And even if you do look older, you are not. You do not have the same experience as a 35 year old, developmentally, financially, and emotionally. Recognize that.

You are still very young. Guys your age are much more likely to love you for who you are, because you are at their level.
