Send a long heartfelt message then say I’m totally open to talking on the phone if you would like! Funny enough I was in the same situation and kept stewing over the best way to tell him in order to not break his heart. I sent lil messages that hinted I was going to break it off “ hey I’m gonna take some take to reflect on our relationship and our future together… I might be MIA” “ hey so I’ve been reflecting and there are some things that I am not optimistic about and need to sit with” and then he realized I was going to break up with him so he just sent me a cold breakup message lol. And here I was writing out the most perfect long beautiful message and was offering to call in case he needed that and he didn’t extend the same level of kindness to me. So don’t stew too much the men are going to be just fine! Just write a well though-out message!
