#2 If you leave the relationship then you will be instantly happy. It isn’t that leaving a troubled relationship isn’t good for some people. In fact, many people are much happier when their partner is gone. The problem is if you love someone and you leave them, you might just find out the problem wasn’t them. Your happiness is something only you control.
Sure, other people make you unhappy. But if the unhappiness comes from within, leaving the relationship you are in isn’t going to make you instantly happy. It might just make you see the problem lies within who you are and your own misery more than anything that someone put on you.
