heartbroken and deflated

I really have no idea what to do anymore, there is no passion in our marriage anymore and we NEVER HAVE SEX. I try everything I can to get a reaction and NOTHING. I sent this hoping for something and I just get let down again.... I've been trying to lose weight hoping maybe that would fix it but again.. nothing

edit: I have obviously tried talking to him on multiple occasions. it seems we come to terms but nothing ever changes on his end.

he says hes tired, we go to bed earlier

he says his back hurts, I give him a massage

he says he doesnt want to do any work, I offer to be on top. (then he just says we will do it tomorrow but tomorrow never comes)

he says it feels forced, I try to flirt with him so it comes naturally and I get turned down the second I say anything.

I have talked to him in depth so anything other than the obvious "talk to him" would be appreciated
