The most important roles in keeping the love alive and healthy. That is:
Understanding - When in difficult relationships, understanding is sometimes the one thing
that can save the love that exists, and when you surrender to it, you will find that its much more fulfilling to bow down in certain situations yielding a comfortable place for the two people involved to be who they are, regardless of mistakes or fault.
Communication - If things get rough, talk to each other. But, while talking remember, UNDERSTANDING AND RESPECT. Try not to raise your voice. If you feel passionate and heated, take a walk, calm down and remember you are here because you love this person. Even if you are not having to deal with hard issues it is still important to talk to each other. Let your partner know how beautiful you think he is or how she makes your heart jump. Reinforce positive things that fill your life with security and comfort, if you want those things to live on. Talk. Make communication a safe place by reassuring each other that within your relationship exists a safe place to discuss anything , even if that "anything" is hard or painful.
Spontaneity - Try a little spontaneity and see for yourself how well received it is. Try coming up from behind your lover while he or she is doing some ordinary house chore. For example if your lover is at the computer working or in the garage etc.. come up from behind them unexpectedly and caress them with suggestive tones. Try telling your partner that you will be busy with the kids all day, then have a prearranged babysitter come by and pick them up sending the kids away without your partner knowing. Find your partner unknowing in an open room all to yourselves and walk right up to them and start to take their clothes off. Tell your partner you have to run an errand together and take them to a hotel room. When your partner wakes up to go to work- set aside 30 minutes for sex. A great start for a demanding work day!
