Some people like routine. And instead of cheating, one should simply tell whats wrong.
This is just stupid. If you need to conciously boost your relationship, it is clearly stressful and should be avoided. Sad thing about it is that you will never know if its going to work or not. All this time wasted, only to break up and start all over again.
Somehow I find that these things are easier for women, bechause usually it is the man who needs to keep up, boost the relationship, do all the work, etc. At least thats what media puts in our mind. Women mostly only need to be there.
