Back to the original question (sorry, distracted by some of the not so nice debate), I do know couples who seem to be happy but who don't attend the same liturgy, and that does cause some stress. More so, if children are involved. I believe children need to grow up well connected to a parish community, but that doesn't mean that people can't visit different liturgies at different times. I do, but as I said before, I am usually at the TLM.
For dating /courting couples who are getting serious, eventually a decision will need to be made as to where the family will attend. That will require much prayer for good discernment by both parties. In my opinion, it may be harder for a person who prefers the EF /TLM to change to the OF /NO as there are elements that would be very distracting in worshipping faithfully. I strongly disagree that the TLM is "nonsense" and that shows a lack of understanding on the part of the gentleman who made that comment.
If the comment about nonsense you are referring to was the one made by David, I think that if you go back and re-read his post you will see that he is referring to the notion that one liturgy is better than another one, not to the Tridentine Mass.
For those of you relatively new to CM, I will point out that this is something of an ongoing issue. There are those here who very much take the attitude that there are the real Catholics who go to Latin Masses, and Latin Masses only, and then there are the slimy Protestants who dare call themselves Catholics but obviously aren't because they go to the devil inspired Novus Ordo Masses. And that's before it goes downhill. Sometimes we get treated to lovely displays of anti-Semitism and other such wonderful things.
Consequently there is some militancy about the notion that one form is better than another.
