Is he planning on proposing?

My boyfriend and I️ have been dating a few months. I’m 19 and he’s 20. I’d say we’re pretty serious. Lately we’ve been talking a lot about weddings and marriage. He’s been asking me lots of questions like what’s my ring size, what styles do I️ like and he even took me to a few jewelers. Is he planning to buy me a ring? I️ don’t know if I️ should be exited.
