luv, don't text him. Leave him be...the yard work can wait and it's not your concern, it's his. Don't text him asking 'you done?' even he's gone for the whole week. Just say 'DS wants to talk to you can you please call him when you get a chance, thanks'.
You create a boundary by not caring about yard work etc. The more you take on the responsibility the less he will. Just let it go, don't even talk about it. The best thing you can do right now is to just leave him to himself and work on yourself. Look good, go out, show that you're full of life and fun.
