BRNR, They are like children in my respects. They see a bright, brand new toy that shines and they want it. Once they get it, the shine soon wears off. The same applies to this new life that they think will be even better than the old life. Many of them will say that it's not what they had expected. They forget that the responsibilities of taking care of a place, bills, children, etc., still have to be seen to. They forgot one little thing...their spouses use to do a lot of those things for them while they worked. Now, they have double the work and it's not an exciting adventure any longer.
As for the way he's dressing...maybe he's left work early and stopped by his place to change. He could be working in a different office that doesn't require dressing up. There are any number of reasons why he's dressing in tees and jeans. Try not to allow your mind to wander and "assume" something. Assuming will get you in trouble every time.
Enjoy your weekend at the beach. You need a break and please try to leave the mlc monster at home. Travel safely.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
