I did it!

I told my husband 2 days ago I wanted a divorce. I feel sad because of how heartbroken he was. He ended up going to a friends for the weekend. I’m afraid when he gets back he’s going to want to try and work on the marriage but I expressed to him I don’t want to and that i want a divorce. How can I make sure no matter what he says he can’t guilt me into wanting to stay? I DONT want to. We have a house together so we are going to have to stay here and basically fix it up a little bit to sell it but will be staying in separate rooms. Do we need to discuss chores as well and who does what?
