When people spend a lot of time together as in marriage, there is the double sided sword of familiarity. This is a person you can be yourself with and be accepted. This person knows you so well that you are predictable.
Be unpredictable. Don't be home when he arrives, call him and ask him to meet you somewhere quiet and romantic. Just the two of you. Dress up, do the hair, the makeup and let him know you are not wearing panties.
Be sure to appreciate his appearance, when he does something for you or the household and laugh when he tries to make you smile. This invitation from him is letting you know he thinks something is missing. Some spark. Act like you are dating again and take him to the zoo or a quiet park with a picnic lunch (include some chocolate). Send him some flowers to work . All these things will come back to you, trust me.
I have a wonderful man that tells me almost every morning that he goes to be with a smile on his face just knowing I am next to him. He says things that make me feel attractive and loved daily. Day to day life gets in the way sometimes, so does the TV. Change your patterns together, the spark returns.
The investment in your marriage is the best investment you can make for long term happiness. Jobs and money will be replaced, but the time you have with your husband is special, but easily overlooked as easy and comfortable.
Very best of long term happiness to you.
