So so difficult to phrase this correctly! Bear with me please. Grown up son of 22 has returned after living subsidised on his own for 3 years. He has moved back due to giving up uni/relationship break up et al. So far so good. DS has a home, opportunity blah blah for fresh start... Then we find he brings home a young lady to stay overnight that is now staying almost every night without a word to his parents. This is the difficult bit, we state what our rules and standards are, he more or less ignores it, but is not unpleasant, just laid back. So frustrating. He has the ability to support himself so no worries on that score except that he has no incentive to leave a comfortable home. He needs his own place to do his own thing so we don't have to see it iyswim. If you have experience of this situation I need to hear it to regain perspective. Happy New Year.
