Has my boyfriend moved out and moved on?

We dated about a year but I have know him for decades. The plan was for us to live together in a house he was going to buy in my area which is cheaper. He moved in with me while we looked and then ended up moving out 3 months later because this area effecting his health. He swore it had nothing to do with our relationship and his feeling towards me. He has been looking for a home in another area where the climate and altitude don't effect his illnesses. This separation is only supposed to be temporary. After two months he hasn't bought anything and has only found a few homes to even look at. The issue seems to be where he wants to live is too expensive and he cant afford it regardless of what size home he was looking for.

Here's what's bothering me. He moved out to stay with his parents temporarily but now feels he dad is too ill to move to far away from but cant afford to live in their neighborhood. I wanted all of use to move together and rent a place until we found one to buy. He had a long list of reason why that wouldn't work out. If he wants to be with me shouldn't he try and keep us together? What does it mean that he moved out without us? I'm rent and if its just me and my kids I would move to a cheaper smaller place but im hold to see what he is doing. When I suggest he looks for cheaper areas to buy in he gets mad. Is he making finding a house impossible so it wont happen?
