Just want to get it off my chest

I've liked this guy friend for some time now. We've been in contact on and off in WhatsApp for about a year. We used to live in the same country but then we both moved for professional / personal reasons.

Anyway, I think I've reached a point where I dont really care if we're ever together and if he likes me back or not. The only thing I know is that this feeling is strenuous and is taking its toll on me in the sense that I got tired and that I kust want to get it off my chest. Dont know if I should do it (tell him) and would like to see if any of you has had a similar experience and how you went about it.
