MY ANSWER: There are times when “really nice” isn’t really nice for you. If they don’t have the same goals as you do “really nice” can eventually turn out to be “really devastating”
We should only date with the intent to see if this person is a person you could marry. Anything other than that can be a great time waster and added temptation to give your body to someone who will NEVER marry you. My advice would be to shake his hand, thank him for being “really nice” and “really” move on to what God truly has for you.
