Congratulations on being chosen by Ms. Kitty - I have had cats most of my adult life and cannot imagine living without them. A word of caution - cats supposedly prefer being an 'only cat', but since getting two cats about 6 years ago, I find they're both happier and less likely to get into destructive mischief now that they have each other for company.
And congratulations on getting to the place you are at. Yes, recuperating will be your major focus for a while, but once you are on the other side, you will need to rid yourself of the negative baggage i.e The Cheater. You are so much more than he deserves - having been there, I can tell you, it's so much better once you get past it! ((((((((((HUGS))))))))))
