FH and I are trying to set a wedding date. It's proving much more difficult than I thought! We have a particular date that would be perfect with our schedules (between work and school it's so difficult finding something). However FH has a sibling getting married two weeks before it. FH said he could ask his sibling if they would be ok with that. They are a very chill couple, and I think they'd be totally honest with us if it bothered them. But is it rude of us to even consider this?
