While each of you is responsible for your own success, you now must consider how your actions will affect your partner's business. Be aware of the things you do and how your actions might create a need for your partner to change their strategic plan. To get space, you must give it first. When your partner takes all the covers it is not much fun. To successfully deal with the regular and normal issues and challenges of the relationship, you must get past the denial syndrome.
Denial is an insidious situation that generally results in personal destruction.
The problem with putting your head in the sand is that you leave your posterior undefended. Too often in conflict, it's easier to ignore than confront. A confrontation does not have to be a knock down drag out affair, especially if you selected your partner well. Often communication is key in dealing with missing covers, or anything else. Remember if you steal your partner's sheets today, they might take yours when you are cold and in need.
