How can a married couple of 20 years keep their marriage alive.?

It was a shot gun wedding but we do have 3 wonderful children and both wanted a family. We are devoted to our family, its just that he's in school and always working. I work. We don't really talk or do anything together but we tell each other we love each other. Any suggestions?How can a married couple of 20 years keep their marriage alive.?
well problem is that it sounds like things are becoming a routine in your marriage and thats going to backfire. what my husband and i do is we devote at least 1 night to ourselves either something we both enjoy doing like dinner and a movie or something as simple as blockbuster night. take advantage of those times to talk to each other about anything like you just would to your friends. i understand you have 3 children and that may be difficult to find a babysitter but both of you have to be willing to do what it takes for your marriage to survives and your family to be together. also another big thing is the bedroom, take initiative in the bedroom and be the dominating one. something that he wouldn't expect so that next time he'll wonder whats going to happen. it's nice to keep men wondering because they like the chase.How can a married couple of 20 years keep their marriage alive.?
take a break spend time together do something you all have not did in awhile try something new like when he comes home from work lay on the table with his food right between your legs or better yet give him some head while he is eating his dinner
