I would like to get my girlfriend a promise ring. Weve both talked about it and we both want to marry each other. I just don't know what to get her I am not in the best financial situation atm. I would like to get her a rose gold ring and a ring for myself any tips. I would like to add a custom engraving with a few words with the date we started dating. Im not too sure bc i cant find any nice promise rings. I was looking to get her a darry ring but thats 2000 minimum. What should I do. Any tips would be appreciated Thank you for your time. feel free to call me an idiot
