my fiancé and I have been together for 8 years now and our wedding is 5 months away. We broke up once and got back together after a year apart. It’s been 3 years since we got back together. However, just this week, we had a heart to heart talk. He’s thinking about a lot about the marriage like “what if the marriage between us doesn’t work out”? He asked for 1 week cool off period to think about whether this is really what we want. Please advise what should I do?
