Tested solution:
"男友5.0" 和 "老公1.0" both are buggy versions, none of them can run for long without system reboot. You could try to use "wife 1.0" to match, but that can cause system overload.
Use either "男友3.0" 和 "老公3.0", as they support very similar functions, no major upgrade or down grade required, and can both last for a long time, as long as you have "girlfriend 3.0" or "wife 3.0" to match up.
