ladies please help me

my husband & i have been married for 2 months. we dated for 3 years before that. we both joined the military out of high school (him a year before me) so we have been through a lot. we started having problems before the wedding but went through with it because we thought it would make us better. now here we are, completely miserable. i don’t know what our problem is. he’s just such a negative person & it drives me crazy. he doesn’t even try anymore. it’s just like he doesn’t care at all & it makes me not care. i feel like we’ve been through too much to give up on us, especially since we’ve only been married 2 months. i’m so lost & have no idea what to do or who to go to. i literally feel sick over this. he can just be so negative & mean. he never wants to do anything or go anywhere anymore. i feel like i don’t want to be with him sometimes but i also don’t want to lose him. i just can’t take anymore of the negativity. ladies please help me. i am almost to my breaking point.
