So I’m a 7/2/85 ox who fell hard for a 12/30/72 rat

In order for you to break this soulful connection, you need to be the one to do the moving-on the most. Try not to think about them at all. Give yourself time to go through the process of ending this connection between you and the other person. And in time, this connection will be broken and you would have moved on, same with the other person. Remember, this process is long, hard and sometimes grueling where it asks so much of you. But even so, it's a process so take things slow and gradually work your way to just dissolving this person from your life. Take up a hobby, read a book, occupy yourself.
