It is a highly plausible assumption that she has in the past: She was dating Tiroy for about nine years, and she did share the same bed as Matt. Most likely that will resume once she is recovered. Meanwhile, there is no engagement ring nor talk of marriage, and this is clearly an outlier in her own family, as per her videos.
Another reason she is not a devout Catholic is because devout Catholics tithe to the tune of at least 10% of their income. According to Google:
"
(The word tithe literally means tenth in Hebrew.) Because the custom of tithing is biblical, many Christians and Jews practice it as part of their faith."
Nowhere does Tiffany state that any percentage of her online profits and income is given to a church or even to a charity. Seeing as how Tiffany would probably enjoy being looked upon by her audience in the best possible light, if she did give anything to charity on a routine basis, she would most likely have mentioned it. She did mention making a contribution to the Royal Marsden at Christmas time during a tree ceremony. It seemed to have been a one-time contribution.
Tiffany did mention that her mother goes to church on Sundays, and sometimes on other days as well, but it was not stated clearly if she accompanies her mom or not. I think that her mother is a devout Catholic, yet her mother doesn't make a point of openly praying. (In fact, there is a quote in the Bible that says that showing off to others that one is praying is not well looked upon by the 'Higher-up.'....just sayin'!!) Whether religious or not, many people have commented that they think video-taping and posting her little prayers in the car are not in good taste.
Anyway, it does seem, as you said, as though Tiffany purposely does not inform people. I was curious as to how long her operation lasted, but have not ventured to ask that in current comment sections. Informing people of the duration of her surgery would have been one of the first things she would have said, so I thought. (I expected something like "Guess what? My surgery lasted __ hours!!") Yet, I have noted no mention of the duration of her surgery in any of her hospital videos (not that it matters, but it was just to compare with what is stated in the literature.) She had stated that she lost 'a day' in the very first hospital video she posted.
