Talk to Your Partner
Both men and women need to communicate well on all points in a relationship. Let your partner know that you will need some space and some time for yourself every now and then. Anyone who is sensible will understand the importance of this time and will not have any issues with it. Do make sure that you give the other person the same and when talking about the topic, choose your words carefully.
Meeting friends is a great way to let go of stress and have some "me time". You can have some fun and at the same time discuss if there are any issues being faced by you in the relationship. Discuss such matters only with your best friends though as you can be certain that the discussion will remain between the two of you and you will get some sincere advice.
Hit the Gym
This will help you improve your health and get some time for yourself. It is an important activity as it helps a person let go of the stress s/he may be feeling and is a way of feeling energised.
Weekly Night Out
Both husband and wife can plan separate nights out. Guys can hang out with friends for a game of bowling and dinner while the ladies can catch a movie and dinner or whichever activities they like. It can also be planned for separate nights of the week which is perfectly fine.
Just Sit Around
Just sitting around with no fuss is one of the best ways to spend time with yourself. Listen to what your inner self tells you and try to sort out any issues that you may be having. Sometimes sitting alone quietly feels better than anything else.
