You need to determine whether the problem is in the solenoid or in the furnace electronics. You could put a voltmeter on the solenoid connection to see if the furnace is still holding the solenoid open after the blower stops. This will tell you whether it is the solenoid or not.

sounds like you may have it wired to a continuous power source vs one that shuts off with the furnace. The most common wiring is red to C & white to W

You are absolutely thinking correctly....the humidifier should be running when ever the blower is running and the humidistat is not satisfied...in fact in some cases I have advised people even turn the fan switch on to run the blower longer to get more humidity in the air if needed....some furnaces do not have long enough run times to get enough water evaporated...
You have the idea of how it needs to go, so you should just go ahead and wire it up that way and you'll be glad you did!! You can get a relay for a few bucks and have a much better working system...
