Kids dating before the age of 13 can bad. Why, you ask? If you're younger than that you may not understand why yet. I hope this teaches you something. Dating early can be really bad for your mental health and can cause really serious depression. Because if I'm being honest, not a ton of relationships last when they start that early. That's just the sad truth. Maybe you feel totally ready though, and that's okay. Sometimes, kids don't understand how badly you can break a young one's heart really badly. It could even permanently damage your mental health. So that's why you shouldn't date before 13 unless you feel ready for whatever will come.
