What do think about me showing a lot of concern for my fiancee?
That's nice of you. Why do you show so much concern for her?
I care about them and that's how I show it.
It's good that you show your fiancee how much you care and love them. It's very important to show the people in our lives how much we love and support them.
Eh, but sometimes I'm not sure if these feelings I have are genuine. Do I dislike her? I don't know, but I'll still show my concern.
Caring about your fiancee and showing her how you feel is great. This will ensure that the both of you can move forward in a loving space.
