Just need to rant..

I have this best friend of 9 years.
We barely text or call, but he’s always willing to see me.
I saw him recently and it’s been a long time- I know for a fact, that he’s very precious and important to me, and I’m precious and important to him. This is proven every time we meet- he hugs me tight, he cuddles me, lets me stroke his hair a bit.
He looks straight into my eyes when we talk. Whwn we hang out we’re in complete presence of eachother. He’s willing to drive me and take us out to places. The other day when we met I felt him give me a peck on the neck in between a cuddle.
We have hobbies in common and we’ similar in personality.
It happens every single time we meet for a day- I miss my best friend terribly, and my desire to call and text him almost takes over but I don’t because I know he’s got work and won’t text back because that’s just how it is. I just miss seeing him.
I have a boyfriend I live with I love, but this is a different kind of love- to me, my best friend is so important in life the thought of losing him terrifies me. I whole heartedly believe in his feeling of importance and love towards me as a best friend. I just hate feeling so miserable just after I see him.

What can I do about this??

Thank you for any help that you give!
