My sons are all grown and doing well on their own, however, they didn't get that way without help and encouragement. From an early age they were made aware of the things that needed to be done for a household and a family to function. If they helped me with those things then those things would get done much quicker and we could all play together. When they graduated from high school they were informed that my obligation to support them was over. They could continue to live under "MY" roof as long as they were contributing members of the household. Contribution could be monetary, or physical, but they must contribute. Working and contributing to he family budget still did not relieve them of basic household chores. My working did not make me exempt nor would it them. They also knew that if they didn't comply they would have to leave. It has been over twenty years that they have been adults and we have an incredibly close relationship. I now see them operating their households under the same premise. It's time for some "tough love". You are loving your family more by not being their maid and doormat. Initiate some new rules and stick by them. Force them to grow up. If they don't like them show them the door. "Just an Old Rooster's Opinion". Good luck and God's blessings.
