I feel like I need to respond to this thread, because I have been there once upon a time.
For some context, I’m 32. When I look back at being 16, one thing my best friend and I both wish we had done was stay away from the older boys...I mean men. It only ever brought trouble, and looking back, it’s a huge ick.
Even when I was 19, I can look back now and think, "Would I have had the same interests, things in common, or life experiences with a 16 year old?" No. Because at 19, life is very different from being 16.
A 19 year old man has no business pursuing a 16 year old with the intent to date. That should be a very big waving red flag.
I’m not saying this to judge you or make you feel bad. I’m saying it because I was your age once, and hope you don't have the same regrets, or ick when looking back. Please don’t put yourself in a situation and stop talking to him today.
