I feel like my marriage is failing!!!!!

It's a long story but here we go. It all started a year ago when my grandmother passed. She left me in charge of any of her decisions medically if anything were to happen. This was because I knew exactly what she wanted and wouldn't go against her wishes. Well last year something happened I spent months in the hospital helping to get her better and she passed. Well a week of setting up funeral arrangements and waiting on her body to come from the hospital. All he did was fight with me. I got yelled at for spending so much time from home and away from the kids. He said he didn't understand why I was doing all this when my mom was fully capable.

Well fast forward to this year. I am getting accused of cheating because I get called into work. He doesn't believe me when I do even though I show him the calls. I get accused of not loving him anymore. I'm over all of it. I'm still pissed about how he acted when my grandmother passed that hurt a lot. He should have been there for me not fighting with me.

Now we both work different shifts. I work second and he works first. We have two children together and I have two from a previous marriage. We do this because of the cost of child care. I have tried talking to him and all he says is I never have time for him. I ignore him and never want to have sex. Which is not the case but it's hard with four children.

I'm honestly at a loss at what to do because I love him so much but I can't deal with the accusations anymore. I am not happy and he won't agree to counseling.
