I kind of doubt that what's going on with Jessica and Tom Davis is as simple as "Scientology breaking them up."
Tom Davis had a job where he was working for James Packer. He was the manager for Packer's Hollywood studio, RatPac entertainment.
In that capacity, he was undoubtedly reporting back to Scientology on everything and manipulating Packer into doing their bidding. Mariah Carey's reps insist that Scientology was behind breaking her and Packer up. Whether that was the whole reason or only part of it, they were obviously into his business via Tommy Davis.
Packer had some losses, sold his studio, and Tommy was out of a job. No more Tommy working for Scientology influencing Packer. He's back to working for a real estate investor his father knew.
It's quite possible DM blames Davis for Packer's business failings and for basically being kicked out of a position where he - and therefore Scientology - has any influence over him. And, in this case, he might actually hold some responsibility for failings in RatPac. He was the manager, after all.
Once again, Tommy Davis is on DM's shit list.
What any of this has to do with him and his wife breaking up I don't know. He may have taken an income cut when losing the job with Packer. That never helps when you're in a marriage with two small children. And maybe Scientology is involved. I don't know.
What I am sure of is that he is that none of this is a positive for him.
Looks like this article agrees with me.
