Like we've said a few times before, every couple has misunderstandings and arguments. This can be minimized, though, if a couple truly understands one another. A man in love will notice that you're often stressed and moody after a long commute home from the office, so he'll give you the space you need to unwind when you arrive. He'll understand that you don't want to go to his buddy's barbeque when you've received an invitation to go to coffee with a friend.
Basically, he knows the way you work and he loves you so much that he gives you the freedom to be yourself. He wants to help you live your best life, not pressure you to do things that you'd rather not be doing. If you're really lucky, he'll even understand that sometimes you feel like eating a whole tub of ice cream after dinner!
