If your love is a number 8, you should make him feel you are balanced to act as, for this number, except for bad aspectations, there is nothing worse than lack of balance, lack of harmony.
He does not like stormy love stories. He likes to find peace and serenity although he himself may be the one who loses them often.
You should get used to the fact that his businesses take much of his time and if you can join him, there will be no better partner to plan, if not grand, at least important undertakings.
It is very common that people who have a surname with number 8 come from either wealthy families or at least entrepreneurs, businessmen, managers, etc.
So it is quite likely that you must often attend with your partner entrepreneurial or business meetings.
There is no room for "I do not feel like going out", as for him this is part of his life, public relations mixed with business.
As he is always looking for balance, you will also enjoy his happiness for staying in to admire his possessions, the achieved beautiful house and the balance his house gives him.
