Everybody is different so it’s not so much about the actual age you are, but about whether or not you feel comfortable with the rights and responsibilities that come with having a relationship.
As always, to get a definitive answer, you’ll need to ask them. It might be a really uncomfortable and difficult conversation to have but not knowing is uncomfortable too. You don’t know what the expectations and boundaries are if you don’t know how the relationship is defined.
It can feel a lot safer to ask someone out online or through a text message because if you’re rejected, at least they can’t see your face. And it can be easier for them to let you down gently. However, if you’re pretty confident that they like you back, you may feel self-assured enough to ask them face to face.
Because everybody is different, everybody will have different ways of behaving when they like someone. However, some of the more common things include looking at you a lot, finding ways to be near you, possibly showing off a bit when you’re around them. The only definite way to know is for you to ask them.
