Was it obvious you guys were home? Seems weird that if he knew you were home he'd be the only one trying to get in the house. Usually 'home invasions' involve more than one guy (not counting the getaway driver). I guess what I'm saying is that I would have made it obvious that there were many of us in the house and would have loudly yelled at the guy that he was going to get shot if he proceeded with his plan.
Now, with that in mind. We had our front door kicked in a little over a month ago. We weren't home and the moron got away with next to nothing (the wailing alarm did it's job apparently). BUT, I have taken numerous precautions since then. A) I immediately installed "Strikemaster II's" on every exterior door B) I installed security lighting on every corner of the house and C) (and I realize this is not realistic for most folks for multiple reasons) I contracted a welder to fabricate a 'cage' over our front and back porches. They're very sturdy but of course a bit decorative too for aesthetic reasons. I figured that they can't kick in my door if they can't get to the damn things. Now I know that in 'most' places these are completely frowned upon and even outlawed by HOA's (along with burglar bars on the windows). However, down here in the valley, they are very common....not only for security reasons but I think it's a cultural thing from Mexico as well....some of these things are very ornate and attractive believe it or not.
If you're in the country, it may be something to consider.
I'd also get a very loud alarm, visible surveillance camera's (functioning or cosmetic).
I know it's a horrible feeling. Hang in there and just use your head.
Now the thing that I call livin' is just bein' satisfied with knowin' I got no one left to blame
