If a girl told you she loved you, and if you didn't feel the same back would you tell her?

If the feelings weren't mutual, I'd have to tell her right away (I feel it would be wrong not to respond), but preferably in person. If I couldn't do it face-to-face, I'd find another way. But in my humble opinion, a conversation of that serious nature deserves a face-to-face meeting unless it's impossible to do so.

it would really depend but if we were totally on different pages as they say I might feel obligated to say something to her or at least one of her close friends . as to how I felt so she at least knew what was going on .

I would indeed let her know I didn't feel the same way.

Telling a guy off at war something emotional like that is considered distracting. I don't want you to worry about it, but he shouldn't be thinking about that stuff at certain times or worrying about it while in a firefight.
