I believe you should eat dinner with your son, that is way more important than eating with your husband, your son needs that connection and routine, even if you sit with him, but arent eating he could still interpret that differently. i would eat with him, and sit and have conversation with your husband, that should be what is important to your husband, the conversation more than the fact that you are eating with him, or save some dessert or snack to have with hubby. the childs self esteem is more important at this age and connection at meal time with his mommy.
