Deano’s answer to: “How do you tell a girl that you miss her without sounding too mushy?”

You should never tell someone you miss them.

You should, instead, tell them about how much you look forward to seeing them again, about a new view you'd like to show them, restaurant at which you'd like to share a meal.

Giving someone the feeling that their absence is a loss to you is unhealthy, and in some cases may give them the impression that you are weak-willed and needy. Instead, show her that you are a fully-realized person in your own right – that you don't NEED her, but instead WANT her. 

It's like the poem says:

Let her know she's in your thoughts, 

when together or apart, 

and you'll be sure often as not,
to also win her heart.

How do you tell a girl that you miss her without sounding too mushy?
