Nowadays, Ladies from China are care about housing, cars, cash, bank... when they are looking for men. Did he ever talk about his plan for both of you? if not, it is not the time to try sex. it is very for a man to change his mind. See how many single mothers in Toronto! Love yourself is important, do not give up.
it is not big deal. why fussy around? you only accept his flowers and dinner offers,and reject
services? Is that fair? I guess he is a lonely man and has not many chances to find love.
BTW. you are old enough to enjoy sex. You are not asked to marry him anyway.
