Look at the tweet Chris made about telling Jacob to go home.
Nowhere does it say anything close to 'I never want to see you again', it instead expresses sadness, regret, and he seems disappointed in him for something he can't tangibly explain.
I personally think it's someone else behind the scenes talking him out of this using his autistic fantasy escape world.
Whether it's Barb, Kim, Marvin/Canine, Captain, etcetcetc isn't known but the way Chris handled this doesn't seem like Chris.
Chris' autism didn't leave him with a lot of empathy. Look at how Chris reacted in the past to things like his supposed online girlfriend who committed suicide compared to how he reacted to the end of his relationship with JQ and now Jacob.
He's genuinely all up in his feels and he doesn't even know why.
Someone talked Chris out of it which honestly I think is pretty shitty. This is basically Chris' last shot at not spending the rest of his life alone and dying homeless or in a group home. Is Jacob a degenerate weirdo? Yes. But so is Chris. They say Jacob will end up murdering Chris and his mom but Jacob is in his thirties with no history of violence.
Someone doesn't want Chris to find love and move to SF to grow old as a fun loving queer lady in a city where he'll be right at home.
This is literally the best possible scenario for Chris' future and also the most hilarious. Why people wouldn't want Chris/Jacob cocks recorded live from the fag capitol of the country is beyond me.
And if the white knights are right and Jacob snaps and pulls a murder-suicide who truly gives a shit? It's a fitting end in fact of course.
