You weren't living with your husband during those times, because you were just visiting on a tourist visa... you were not legally living in the same country as him.
So, your answer to the question about whether you have ever lived together should be NO. And your reason for not having lived together will be that you live in different countries and cannot legally live together yet.
This is a perfectly normal answer for the visa application, because they are not expecting you to have been able to live together yet.
If you say YES to living together, you are then required to produce evidence of living together, in the form of tenancy agreements, bank statements, utility bills etc... but you can't get those things as a visitor, because you were not legally living in the UK.
