Not bad, but a promise ring isn't much and a little chicken. I don't know your age or how long you have dated, but if you are over 21 and have been with this girl 2 years or more a promise ring is poor form. If you are serious step up to the plate and give her more than a promise.
Promise ring
when you give a girl a promise ring,a good thing to do is to be romantic. Like putting 365 things you like about her in a jar so she can open one up every day.
It is very rare these days for a boy to give a girl a promise ring. They don't sell them in jewelry stores either, and they are very difficult to come across. Promise rings are very old school but do still exist.
