If you really care deeply about all those things then do nothing until your startup has succeeded or failed of it own accord.
Business is business, and that should be your primary concern at this point. A startup can have an interesting dynamic, with very close working relationships, stress, etc... It can cause people to rely on each other in ways they wouldn't normally have to do and thus produce feelings that aren't necessarily mature.
There's really no "good" way to deal with it. The best way would be handled it after the business is up and going, but it is still likely not be be a good resolution. Someone will be hurt.
Then there's the quite unlikely event that everyone is sufficiently open-minded and a nice polygamous relationship will develop..... this would be the most unlikely option.
