People have a pretty big tendency to think that everything that happens, involves us in some way. It is called "Personal Importance" and is hard to get rid of.
When someone close to us does something good or bad, we tend to think it is about us. We need to realize that while we are a big part of our partner’s life, they will do things for them too.
If you take every action they do personally, you are sure to go crazy and will probably feel unloved.
Being more understanding of their emotions and feelings and trying to realize why they do the actions they do is a great way to get past our personal importance. This doesn’t mean they can get away with hurting your feelings, but it does mean that they do have a chance to do things for themselves as well.
