My husband and I have a date night every single weekend. We feed the kids earlier than usual and have them go to their rooms to read before bed. Then we make a fancier-than-usual dinner for just the two of us and watch a movie we've TiVo'd. Every now and again we go out to an actual restaurant and a movie in an actual theatre, but for most date nights, this suffices as a way to concentrate on just the two of us.
Do something that lets him know that you are thinking about him when he's not around. Buy him something you know he would like (doesn't have to be pricey.) Slip a love note or card under his pillow.
And if there's something that he does well (that you can talk about in public...) brag about it to your friends. When it eventually gets back to him, he'll feel ten feet tall.
Get a blank journal. Write a love note to your spouse. Make sure you date it. Then place the journal is his night stand drawer. Tell him to write you a note when the mood strikes him. Then he will place the journal in your night stand drawer. Keep the journal going for all the years of your marriage. Don't expect frequent entries. Read through the loving thoughts when things aren't going well.
Communication is key but can get lost in daily life. Make sure you take a time out to reconnect by having a weekly date night. It doesn't need to be expensive or even romantic. Sometimes my Sweetie and I just do the grocery shopping together. Just do something where you can talk to each other with no kids around.
