Secondly, no it's not wise. You can keep it imaginary like a waifu but if you go too far into caring about the roommate, which is the natural progression for most, you will inevitably be hurt. Even without a yab, you will not be satisfied and want more, either attempting to groom them or being jealous of other viewers etc. It is simply not sustainable, it may last a few years not more, and it will rarely end painlessly. My advice is either keep sufficient distance or don't even try.
You may rationalize it in many ways like this is better than nothing but this is simply not how this works. Love is like a drug and it's hard to not get addicted.
