I need advice and help about my marriage!

My husband and I have been married for 2 years and we have been fighting almost everyday, he works out of the state and I’m a SAHM we both have a one year old together. But after he was born our relationship have been going down lately. We fight over money, we fight over our son, we fight over small things. And I have tried to talk to him about our problems and on how we can solve them but he ignores me and doesn’t want to talk about it instead he brushes it under the rug and just leaves it. I have tried to fight for our marriage for so long that it’s actually tiring me and draining me so much. I don’t eat a lot like I used to, I can’t sleep most nights and I have let myself go completely. I don’t have motivation for anything. I’m just tired but I want to work things out. Any advice??
