How can I save my marriage??

Just warning it is kinda long. Okay so long story short, me and my Husband have bad 2 back to back miscarriages and we haven’t had any luck conceiving since our last one Back in April and it’s definitely put a strain on our marriage. We don’t ever talk anymore, we are not intimate anymore hardly at all, we hardly ever spend time together. He’s constantly on his phone, his PlayStation, or messing around with his truck.. pretty much just anything he can do to not have to be around me. Well here lately (last 3 months) we’ve only been having sex 3-4 times a month and everytime we do I hate for him to touch me . Like when he goes to touch my vagina I flinch and when I finally let him I feel NOTHING at all. No pleasure, no emotion. It’s like my clit is paralyzed and can’t feel anything and all I can is pray that he’ll quit touching me soon. I seriously lay there like a dead person. I don’t what’s going on with my marriage but I don’t feel like it’s gonna last much longer😔😭 any tips on how to save my marriage would help. And before anyone says try talking to him, I have multiple times and all he says is “well idk what to do” “I don’t know what’s wrong with you” like it’s my fault.
