Brooklyn, I was also told not to give my husband his ring in the yichud room because then it would still be like us bartering for marriage, rather than him giving me the ring (especially because his is worth more than my wedding band).
Kiruvwife, when you are ready, I am more than willing to debate that point if you disagree (I know not everyone does). I hear both sides of the statement, but lean more towards kollel being a luxury.
