Brothers - haven't talked in over 5 years.

My brother and I do not speak any more...his ex wife was sending me nudes..and I was sending some back. They have divorced and he is re-married. His current wife told my wife that I was doing this..because they used to be best friends (the ex-wife and the new one) they are not anymore. My brother texted me over 5 years ago and told me to fuck off....and that killed me. I know I was wrong..I regret more than anything doing that. there is alot to unpack there..BUT I miss him like crazy lately, but not sure if or how the reception will be, and what that would mean for my marriage. We have been married for 19 years. together 22. I have spent a tons of time in prayer about this, and have tried to change the way I look at things and my actions. Just loooking for some advice.
