If your husband or boyfriend is out working on the car on a hot summer day, make a thermos of ice-cold tea and take it to him, giving him a gentle kiss. Just because the flame has become a mild flicker, that does not mean you have lost the love for each other, it just means you need to add a little fuel to the fire. When your mate has done something that requires you to forgive, you have to forgive, REALLY forgive.
As your mate makes new friendships, encourage that growth and show 100% support!
It will take some time so be patient. You will truly be amazed at what this can do for your relationship. This will open up for long walks, taking your new dog on a walk, or hours of playing with a sweet and funny cat. Think about it.
It is important not to let yourself go, even when your relationship reaches a comfortable state.
