How long should I wait to hear from this guy?

We met months ago and I told him I wanted to be friends at first to get to know each other. We went out 3 times and then his mother became ill and we fell out of contact as he was spending all his time with her plus he has a very busy job. Then a couple of weeks ago we got in contact again and he invited me for a coffee last week. We got on great. I was telling him about a friend's wedding I had been at and he said 'now we'll have to get married. Aren't you going to marry?' I smiled 'I'm on my own at the moment'. Then I was telling him that I'm having problems in the house I'm in at the moment and he said 'you're welcome to come over and stay a bit in my place'. I said 'where will I sleep?' He said 'on the sofa'. (I've been to his place before and he was very gentlemanly and respectful. Last Friday we spoke and he said that this weekend I'm invited to his place. I told him I enjoyed our get together and I could hear a bit of embarassment in his voice. He's quite reserved. Then I said 'ok, you call me as you have a much busier schedule than I do at the moment/ He's not the type to openly compliment but he is very kind to me. I also mentioned I'm taking salsa clases and he said he wants to come with me one time. We're both 30+, single and no children. Do you think I'll hear from him? When, seeing as he said we'd meet this weekend?
