I hope your family and wife are supportive..
I bought several large lots of cards earlier this year, probably totalling 750,000 cards or more, and I quickly fell out of favor with the wife and family once they saw how many I had in the basement..I sorted out all of the baseball cards within the lots (with the help of our youngest daughter) and it was an overwhelming task which took all the fun out of collecting..
I then got an out of state job offer and it was a scramble to sell what I had left ( and luckily sold most of them) before we had to move..
So as someone who has been there, don't let the addition become too strong, enjoy the hobby!
