How to tell my husband I feel zero sexual desire towards him?

Multiple reasons:

1. I’ve been depressed and anxious most of this year. (He knows, and just recently told me I was being “too negative”).

2. He has put on a lot of weight and recently I couldn’t even feel his penis in missionary (he was already small but the extra weight has made it worse. When he sits down it retracts so much it’s not even an inch).

3. He has been mean to me (emotionally) and does things that made me feel emotionally detached.

4. He doesn’t really do any effort to prepare for the moment, he’s just like “i want to have sex”. I mean, at least let’s go on a date.

5. He looks at me like a piece of meat. I just told him I have cramps because my period is due soon, how can you look at me expecting sex when I’m in pain? And he got mad.

6. He’s kinda gross sometimes. Just now I had to point out the shirt he was going to sleep with was very dirty. He wipes his hands with his clothes sometimes. And here I am, taking care of my body and appearance and he’s just there existing expecting sex.

7. He recently said he doesn’t want to have kids because he’s 32 now and feels “old”. So… where is this marriage going to? I have no sense of direction in our lives.

The last couple of months I’ve done it because it feels more like a task. He also told me “ahh I’ve had to masturbate in the bathroom, because I can’t take it anymore”.

Side note: I’m not having an affair, there’s no one else, I don’t even masturbate anymore. This has never happened with any significant other. My sex drive has always been high.
