>you will never have your cute, tender girlfriend squirm around in your arms and adjust her position beneath the duvet cover until her body can get no closer to your own then kiss the smooth skin of your inner wrist and whisper "goodnight Anon, I love you"
>you will never feel secure in a relationship with someone who you know, due to some kind of instinct that you needn't even question, loves you and sees you not only as their lover but as their best friend, and who you know you will care about to whatever extent for the rest of your life
>you will never have someone be curious to learn more about your life, about your likes and dislikes, and about your often niche and highly personal tastes and hobbies just for the sake of knowing more about you so as to have more of you to love
>you will never dress in smart clothing for a formal dinner attended by people you largely don't know but are associated with due to your employment or academic studies, and have your girlfriend tell you not to look at her until she's done dressing and finally remove your hands from your eyes and see her standing there all dressed up waiting quietly and vulnerably for you to tell her that she looks pretty
>you will never lie shirtless in bed and hold your shy, quiet love in your arms and silently communicate your mutual affection without saying a word or altering your facial expression
>you will never receive consistent, subtle, often-humorously expressed but ultimately serious and genuine encouragement from a girl who perceives your potential and is unwilling to allow your self-doubt, self-loathing, tendency for self-sabotage and occasional lapse into nihilistic apathy to prevent you from being all you can be
>you will never hear her say "I do"
>you will never make her proud of you
>you will never make her feel lucky to have met you
