Emotionally drained...

I feel like me and my husband fight over the stupidest crap..But here lately it's been about his parents..We don't like each other..It's literally stressing me out so much I can't take it anymore..He's always defending them and never defending me..Kinda makes me feel like we should no longer be married..But we are also about to have a baby and he can drop me so easily I just feel like he shouldn't be with me if it's that easy for him to leave me..
