You can't be in a committed relationship 95% of the time. When you've committed to someone, it's for a 100% of the time. All of your behavior and decision making should be with consideration of your significant other. Remember, you're in this to create a life together. Yes, you can make mistakes but you don't want to make the sorts of mistakes that say, "I'm going to just do what I want." The minute that you feel yourself thinking that, you are behaving as if you are single, like your actions do not impact your partner, like your partner's
feelings don't matter. And if you persist in this vein, eventually your partner will hear you saying "Don't have
expectations of me" or "You shouldn't care what I'm doing." and they will begin to treat you
the same way. Do yourself a favor and call it a day.
But if you are determined to win forever with them, try to remember back to a time when THEY were what you wanted. Remember the thoughts. Remember the feeling. And instead of doing what you want to do, start first with, "Hey, what do you think about this? I want to get your input."
