People get married to stay married. No one gets married to get divorced. Unfortunately, often people choose business partners with more care and screening than they do marriage partners. Pick any crisis that happens during a lifetime and picture the different responses. Go and talk to intermarrieds.
Love is open-eyed, infatuation is blind.
If you think love will conquer all, then you are infatuated. Try a trial separation. Go your separate ways for three months, date others, don't communicate with each other. If you really need to get together you will. I suggest you learn more about your heritage in the meantime.
