@IknowwhatIneed I am so sorry for what is happening. I know exactly how you are feeling. My now ex applied for the apartment here in our coop complex and waited for it to come up, but in the mean time when I was asking him if he was looking elsewhere he would tell me the same, that it is all so expensive and so he will only move out if he gets the one here. In the meantime, I was looking every day and found tons of interesting apartments that were a bit more expensive but still acceptable, and kept sending him links to it. Same as yours, he would not even comment. In the end he literately told me he is not moving unless he got something here, so I started looking for something for me and the kids.
Luckily, an apartment came up here in our complex and he moved out three months later, but it was nerve racking. I also slept on the floor this entire time and he did not want to tell the kids until he knew that he had a place to move to, so I was always worried that they will come into our room and find me sleeping on the floor. I thought I was going to get a nervous break down or cancer, that is how my health got bad in those few months.
They know we want them to move out and are taking the opportunity to torture us some more, for a little longer. Yes, bastards. Even after he moved out, I was trying to be civil. Would ask him how he was, send kids over with things so that he would not be lonely, but he mostly never replied and was acting really cold and reserved. Luckily I am in therapy and my therapist told me to stop doing stuff for him, worrying about him, asking about him and I did. Our kids are grown up so we do not have to arrange anything. A few things I asked him to join us, like kids b-day dinners and such he refused, so now, I literally do nothing. It is mind-blowing to me, truly, but I do not even think of him and if I do, there is no emotion, just a huge relief that he is not around and I do not have to take on his grumpy, sulking, angry, complaining drama stuff any more.
Hang in there OP. I find that the period between telling your husband you want out and him actually leaving (and a few weeks after), is absolutely the worst, but it gets better, slowly but surely, once he is gone.
