you are right. They are just like what you are saying.
They had too many girl friends before he met with you, he must have known that who is suitable to be his wife, if he chose you to be his wife, that means that you are his fina choice. you don't need to worry he will find another girl and also he will care you very much, more than other regular husband.
If you find any body like the person you are talking about, so take this chance to get him to be you husband, don't loose this opportunity.
