Your wife wouldn't be angry at you if your projects made money. Your track record so far is spending a lot of time on projects that you don't complete, so why wouldn't she be angry?

Pick ONE smaller project that adds enough value to a user that he will pay for it. Drop everything else. Try to find the right partner, but don't wait around. Have a timeline and income projections you can show to your wife (and yourself). As long as you meet your targets, then everything will be fine. Actually finish it without quitting. Make money. All else is denial.
