Im in a similar situation, but very different at the same time. my opinion is that you are both overwhelmed with your lives right now. he feels hes always working and you feel you are as well..with your son. maybe he doesnt see you as working bc you are a stay at home mom. the gym is an ok outlet, at least it is not drinking or partying..but still frustrating. maybe you two can plan days he gets to go to the gym, and days he stays home and you go visit your mom or a few friends without your son. as long as you both stick to the plan you will both feel better. one date night a month and one family day a week can also be planned to meet all of your needs. and doing something he likes as well as you. i dont think he is abusive, from what you wrote.... but i also think the fighting is obviously weighing heavvily on both of you. both of you need your needs met and allowing him alone time will give him a chance to give you alone/or family time. its all about balance but both have to agree. this is where my problem comes in so i dont know much about that lol. the man has to stick to the plan you too make. with a goal in mind and a plan..the arguing will subside as needs are met!!! good luck!
