Give Each Other Space
Part of getting a relationship right is knowing when to give your partner some space.
Relationships are great. They create stability and give people a sense of belonging. At the same time, people need a break. People need to have some time just for themselves.
To maintain a healthy relationship, it is important to give a partner some space when needed. One of the worst things you can do in a relationship, is be clingy or interfere when a spouse needs some time alone.
Some people just need a few minutes to themselves when they get home from work, some people need an evening to do something on their own, and some people have an even greater need for autonomy.
Just because someone needs some downtime, does not necessarily mean that there is a problem in your relationship. The more you allow your spouse or partner to have some time to themselves, the more happy they will be when they are with you.
