Is it possible to wear a promise/commitment ring on your ring finger without any thought/goal of marriage in the future? Sort of like the ring is a sign of the commitment rather than marriage.
Of course it''s possible, but I think you have to realize that if it looks very much like an engagement ring or wedding band, people will generally assume you''re engaged or married. If you want to avoid this, you might want to choose a different style ring. But in reality, even engagement and wedding jewelry is only a symbol of the emotional (and legal, in some cases) connection between two people. There are plenty of people who wear decorative rings on their "ring finger" just because they want to and for no other reason, and plenty of engaged and married people who don''t wear rings at all. If you decide to wear a ring as a symbol of your commitment, who is anyone to say you can''t? Unless you''re personally uncomfortable with the idea, go for it!
My daughter wore her (former?) promise ring on her right hand, but a lot of people still assumed it was an engagement ring.
You should wear your ring(s) on whichever finger you like. Other people may or may not attach a particular meaning to it regardless of which finger it is on. I would ask the BF which finger he preferred it to be worn on, maybe?
Most people will assume you are engaged if you wear the promise ring on your ''ring'' finger. And when you first wear it, people will notice it being on the ring finger and make comments. As long as you are comfortable answering these questions and telling people that it''s not an engagement ring, then by all means wear it on your ring finger. But if these questions are going to annoy you, then you might consider wearing it on another finger. It is all to do with your reaction when people assume it''s an engagement ring.
