My husband and I barely ever...

Sleep together anymore, usually we are fighting about dumb arguments/comments and he'll sleep downstairs on the couch and we just got married 2 months and 11 days ago... I know it shouldn't be like this... What can I do to help my marriage? 
The first month we had sex like crazy, the next month slowed down quite a bit and this month has been pretty much nothing happening in that area... Is it just me?? help! 😓😓😓
