I think this advice is wrong,sentimental claptrap,I don't see anything wrong with your expectation that he pulls his weight and doesn't continue to use you as a cash cow.Wanting to make it big in music is his ego talking,if he were any good at it he'd have made it by now or at least be making a living out of it.The truth it seems to me is he is deluded if he thinks it is still going to happen or he knows it won't and is out of ideas how to earn a living,he is a one trick pony whose time is running out,the dream is fading and I think you have been there for him enough.it isn't emotional support he needs it is tough love.kick him into the here and now and show him you aren't his indulgent mother unconditionally hanging to cater to his every need while you shoulder all the burdens and make all the sacrifices.I can't believe someone is advising you to be gentle with him and support him emotionally,you already give it all financially.You work 50 hours a week he can't be bothered to take the cat to the vet,and someone is now asking you to give your few precious spare time to emotionally support the loser layabout as well.Well if that is love nowdays stuff it,I thought partnership was equal contributions equal responsibility anything else is dependency,resentment,and negative emotions.
