Well, you don't tell him - just yet. You try to work things out with your husband. I agree, its tough to have a long distance relationship. As with any relationship, if you don't put time into it, you can not develop it. With your husband being away, there is a part in the relationship needs that are not being met. You mentioned that your still love him but aren't IN LOVE with him. Consider this, the feelings and acts that you were able to display to him while he was present, made you FEEL IN LOVE. Since you aren't able to display those feelings on a regualar basis, its almost as if those feeling dissipated. Well, when you FELL IN LOVE and agreed to start a family, said your vows, and if they were the traditional vows, you said, through the thick and thin, death due you part... Well, this is the thick. Perhaps, you two should come together again, work on a plan that will allow you to be together, raise your son, and keep A FAMILY VALUE of togetherness be centered in your relationship. One thing that you don't want to display to your son, is that in a given situation, if things are not convenient, then just Quit! That's not a healthy value system. Do what you can to save the relationship and stay together - that's a more valuable moral and lesson in this situation. I believe your son will live out that principle one day when things get tough in his marriage - because WE ALL HAVE TOUGH DAYS! But, things seem to work themselves out when we stand on good values.
Best of all to you.
