Question: are you capable of replacing the money your BF takes out of his savings? If you could some how save up, say $7500, towards the purchase of your first home then the fact that the ring cost $15,000 is pretty minute.
Having your parents pay for the wedding will be a huge help, but know that there are so many extra expenses associated with starting your lives as a married couple. It seems like you can in fact afford the engagement ring and you should be able to enjoy it. Though, will you not be getting married until after college? Just because you are studying for a high paying job does not mean you will actually get a high paying job. If you can't wait until after graduation, I would suggest spending $10k on your ring now and then upgrading using Tiffany's policy to $20k after you actually get settled into your careers and know what you can and can't afford yourselves in the long term.
