Search Results: losing best friend

I've never had such a meaningful relationship as I do currently. My relationship is currently long distance and it seemed to start with an unreal amount of texting, snapchat, and extremely lengthy phone calls and skypes. I do believe I may be worrying myself for nothing here.

She is in college while I have graduated. She still makes sure to call me every night, sometimes up to 3 times in a day. She still texts me good morning most mornings, but we do not have a conversation constantly throughout the day nonstop as we did at first. It feels as though our communication has lessened and our conversations are filled with less "I miss you" and "you're the best" etc. etc. However, she still does reach out to me, and she has called me every night without fail for the last month and a half even if she went out with friends that night and is just on her way to bed. I wanted to get opinions because I feel like I am worrying too much and my own insecurity and overthinking may be ruining the relationship for myself when I should be happy and content.
