I edit my posts often. Improper grammar irritates me.
In our case, my uncle and I both like to read so we often talk about books with have recently read. Movies are also good. And when I send notes, I try to keep it about the small stuff - like, today I went for a walk and noticed the cherry trees were in bloom. Sometimes I refer back to shared memories about were we both grew up - the ocean, beaches, our high school even. Slowly I think we are building a rapport again.
Do you know his hobbies? Do you know much about where he lives? What books he reads or movies he watches? Try keeping it low key and not too personal to start, that's been working for us!
But I would make sure your communications include some pauses.
Separated, divorcing, moving on.
I edit because I always make typos.
