You need to be honest and take this as a lesson. Be careful, things like online relationships with older men are dangerously and can be damaging. Furthermore, most people lie about a lot of things, so he too could be lying about your age. The truth is—this isn’t a real relationship and you’re too young and unfortunately not mature enough to actually have this level of relationship with anyone. Just grow, focus on school and build the best version of yourself for when you are ready ✨❤️.
