feeling distant

my SO has been working two jobs..witch don't get me wrong I appreciate it because he does it for us but it seems like I never get to spend time with him anymore whenever he is home I am at work or if we do get the same time off .. he takes off to do something with/for someone els.. I can feel it taking its toll we feel so distant have been fighting(we hardly fight) like all the time and haven't had sex in almost a week(usual at least everyother day).. I don't know..I ..just feel really lost today..😶
