Does "now that" mean "now so"??
Despite whatever spiritual benefits it claims to specialize in, we all know that Scientology has one especially huge specialty: DRAMA. Resident Dancing With the Stars hunk Maksim Chmerkovskiyrecently appeared on Andy Cohen's basement webseries Watch What Happens: Live where he lamented that he and formerDWTS contestant Kirstie Alley are no longer friends. The reason? Complicated but juicily star-studded. See, ever sinceLeah Remini renounced her membership to the church (which caused Alley to publicly deem Remini a "bigot"), she's been hanging out with bestie Jennifer Lopez way more. So that obviously put Chmerkovskiy in an awkward situation with Alley when he began dating Lopez. See what I'm saying? Complicated. Anyway, yeah:

[Kirstie Alley] stopped getting along with me ... We had a great relationship … But I got a message now that I am associating with other people that she can’t be associated with, I am no longer to be spoken with, and sorry, but it is what it is.

Answer

"now that I am associating with other people" essentially means "because I am associating with other people"

We never use "now so" together without a comma between them, "now, so..."

So is a conjunction used to join two clauses, "I'm on a diet now, so I won't eat any chocolate."

Answer

"Now that" means "because" or "on account of the fact that".  It refers to a cause or a reason.  "So" would refer to a result or a consequence.  They do not mean the same thing and are not interchangeable.

Please note that we do not start a sentence with "because" but we can start a sentence with "now that".

Answer

"I got a message now that I am associating with other people" may be edited to read: "I got the message: because I am associating with other people now. . . " We would not use "now so."
