You CHOSE to do this work. You do not have to do it. If you choose to? You choose to.
If it is getting old, STOP doing that behavior then. Step back. Become ok managing your own feelings of X (anxiety? worry?) in a different way when they have a thing. Become ok letting them figure out their stuff on their own rather than you jumping in to "help them fix it."
Usually nobody WANTS people to hurt. But sometimes they do. And this is not something YOU caused or did.
- Adam assuming things and not communicating well with Braden? That's on Adam.
- If this Adam behavior bugs him it is on Braden to talk to Adam about it.
- If you are tired of being Adam's "interpreter" or whatever stop doing it. Expect Adam to work on his communication skills instead.
- Braden and Adam not talking about expectations now that they are regularly dating? That's on them.
- Braden offering to sit the dogs and then feeling left out or something later on and wishing Adam would be a mind reader and guess what Braden wants? Those are Braden's feelings to deal with.
- If this Braden behavior bugs him it is on Adam to talk to Braden about it.
- If Adam stomps off mad to take a time out to cool off first? Maybe Adam needs that right then.
Partly YOUR dogs, so I think in future you could get a different dog sitter or just board the dogs even if Braden offers. Just so you are not put in this kind of position. Like Braden maybe bails last minute and then you have to scramble to get a new dog sitter or arrange boarding or you miss the party.
But in general? Stop playing mediator and counselor to both. Start expressing concern more appropriately and back off. Like "I'm sorry this is happening like this" and then letting them figure out next steps without you doing anything more.
Or if you are going to do anything, do something neutral. "Can I get you some tissues? A cup of tea?" That is a comforting gesture without you
actually getting involved in their communication or problem solving. You leave it as THEIR responsibility/thing to sort out.
Let Adam and Braden have these awkward/uncomfortable moments. Let them learn to solve them on their own. Or not. They will either make up or break up on their own. You do not have to intervene, interfere, or do anything.
That is my suggestion.
