Kyle Richards and Mauricio Umansky have said they're separating, and we've learned they're doing pretty much everything separately, including therapy.
Sources with direct knowledge tell TMZ ... the estranged couple is not in marriage counseling or couple's therapy. We're told they're both in individual therapy, but nothing together at the same time.
It seems strange on the surface ... that they're not working on the issues that have driven them to separate, but we're told they are not. Multiple sources tell us ... they just want space -- to explore individually.
Our sources also tell us there are still no talks whatsoever of divorcing ... even though Kyle recently referenced their separation as a straight-up divorce, which was an apparent slip of the tongue.
One source in the know tells TMZ ... "Look, they may get back together, but they may not. They just don't know right now. They will decide at some point whether they stay married, but not now."
As we reported, ... there's no prenup in place ... so, with Mauricio's $100M real estate net worth and Kyle's 'Real Housewives' earnings, the division of their assets would really put some accountants and lawyers to work.
