Signs he is going to propose?

Al

Hi ladies! So my boyfriend is getting a hefty $15,000 next month between selling his old car and a real estate commission check, we have been together for a year so I'm curious to see if he uses any of that money to propose around valentines day! What signs should I look out for?? :)

Edit: yes we have only been dating for a year but we have been best friends for 4 years now so we do know each other very well :) thank you for the concerns though!
