Back to square one ?

Back to square one ? That's where we think we are. Last weekend we were suppose to meeting up with the guy on our house to sign papers and get the keys. This week we were going to be moving in. When we showed up for our scheduled meeting he wasn't there. After many messages and days later his secretary finally called to say he is held up with his sick mom at the hospital and she needs surgery. Told us that he will call us when he is available. It has been over a week since we have heard from him personally. Even more weird is the realtor wouldn't tell us anything either. (He is friends with the business/home owner) Something doesn't seem right to us. We are wondering if God is just trying to spare us from something and delaying the process until we get the hint. Not going into to much detail because I need to get ready for church. Please pray that God gives us wisdom and leads us into the right direction. We are really frustrated and just want to settle down for once.
