The best way to show your husband that you love him, is by providing him with respect. Do not belittle him to your friends, do not make him seem small in front of yours or his family. Allow him to be a man. Remember your place in the family. Remember that he is the head of the household, do not make decisions on your own that affect the family, but make sure that you allow him to make the final choice. Never ever make him seem small in front of the children. If he is a good man, you can do all of this without diminishing yourself. A good strong husband will always regard his wife's and children's wishes in decisions that he makes. Not saying that he will give you everything you want, but that he would never purposely make a decision to harm you. - i hear how couples speak to each other...the language they use, the disparaging tone of voice, the words they choose...all in front of friends, family, and acquaintances, even strangers; i am amazed at the complete lack of respect shown to each other. to show Love, start with respect and find out what else that will lead to!
Sometimes a touch, a jester of effort, like surprise him with a treat in the lunch, something that arrives just when he might need it. If he is working hard take him a glass of water. The little things add up. But your touch, and kindness will always win. Then if it is not returned in someway he is just dum and will never figure it out so make yourself happy and move on.
