<human>: Can you give me the gist of the text in a nutshell?

I met him at the beginning of this year,  started out as friends and kinda fell into a relationship.  He's kinda been my first in everything except a kiss. I'm still kinda wary about sex due to my family's..  Grooming. 
He understands and is fine with that. 

He's my first real relationship and recently I've started to think I love him.  My heart skips a beat when he tells his cat he loves it.  Pathetic,  I know. 

We're across the country from each other right now due to summer break. He's recently hit a depressive patch as well as a bad health stint. 

I don't want him to think I'm saying it just because it's what I think he needs to hear.  Or something along those lines. 

And..  I don't wanna text it to him. Because..  That sounds really cheap. And..  I don't know if I can wait till September for us to be physically face to face.  

Should I call him? Should I make a big deal..  Or should I casually say it St the end of a call or Skype? 
I'm confused and now I'm afraid I sound like a teenager.
<bot>: dating a guy for five months,  should I say the the magic L word,  and if so,  how?
