Here are three ways to help with perfectionism:.
1. Accept that you are perfect (or encourage your partner to believe this) just the way you are. The problem is that you have slipped away from this belief. Work on your self-esteem or help your partner do the same, as this will help you appreciate yourself more.
2. Look at any tendency to control people and situations as this is often associated with perfectionsim and obsessional behaviours. Go to the Lovecoach section on control for help with this
3. Recognise that ultimately it is only your relationships and the quality of love that is given and received that matters in life. if you want to perfect something, make it your relationships. If you can do this you will become much happines and your desire to make material things perfect will fall away.
If the perfectionism has reached obsessional levels you will need to seek professional counselling help to find out the root causes of the problem.
