The thread is about dating.
Not those already married.

However apostasy/heresy is grounds for separation.

I believe the difference between sedevacantist and R & R, or even indult should be less burden in marriage, than with Novus ordo, even conservative not liberal NO wife or husband.

I'm in that situation, when I converted to true, trafitinal catholic faith, so many things I needed to "recalibrate". And that brought many tensions with my wife, we both say we do have a different religion and that is true, fr. Scott was right. My mother also, she doesn't believe that ex cathedra pronoucements are infallible, that Holy Ghost is speaking through him like He spoke through apostles. And many other stuff, even when I showed contradictions from Vatican website between some encyclicals, or Council of Trent and Vatican II council.

It's a hard cross to carry, and very likely could lead to divorce if both wife and husband cling to their faith with resolution and conviction. Also when raising and educating children, there are differences, from sacraments to other daily things....

If I knew this would happen to me, I would rather be alone or marry a trad wife. But I can't now abandon my cross and vow we made before God and people. We have a 2 year old daughter, she is very sweet, intelligent, she needs both parents. I'm stopping to be preachy, apologetic, that didn't work. I need to be more humble, praying more, making real penance and sacrifices for their conversion. My work is nothing without divine grace.

Also does your wife hold Catholic beliefs about contraception, abortion, marriage, education of children? If she does have the basic traditional Catholic beliefs but attends the NO you can accommodate that. One possibility is to find a Latin Mass in your diocese… if possible and both attend that. Ask her what it is about the Latin Mass that puts her off… it may simply be that her friends and community are in the NO parish..??

I believe that the reason for the scarcity of decent careers and marriage candidates is that God is willing more people enter religious life.  Especially young men. 

You could be right, but again, which religious societies do you have in mind? No matter how wide or narrowly you define “Resistance,” there are very few from which to choose!  Excluding those who are fully attached to Rome, ie, Indult, FSSP, ICK, etc. Who is left? In the US, you have SSPX, SSPV, CMRI, MHT/RCI, SGG? Then there are Frs. Hewko, (Bp.?) Pfeiffer, the Dimond bros,  “pope” Michael’s brother, don’t know his name!, Does anyone know of others that are reasonably stable, like have a structured course of study, a bishop, a rule of life that’s followed? 
Outside the US I only know of a few, like SAJM in Avrille, -need to be fluent in French, Is Bp. Zendejas connected to it?, There are independent priests here and there, Fr. Ringrose and Fr. Libietis, Fr. Isaac Relyea, (not sure of his ordination status), Fr. Dardis, Fr. Voigt, latter two may not be in public due to health and other issues, but do not have any type of religious institution. In Canada, there’s Fr. Girouard whom I believe is independent, He does speak English but preferred language is French. In Mexico, Fr. Ruiz who works with Fr. Hewko. I do not believe he has seminarians or potential religious. If he does, one must be fluent in Spanish. There is Bp. Tomas Aquino in Brazil or S. America. These are monks, Spanish speaking, Fr. Chazal’s “micro seminary” in the Philippines. There’s a Fr. McDonald in either EnglandIreland or Australia/New Zealand, no idea if he has religious, also there are some traditional priests in Nigeria about whom I know nothing other than they are up against early Church style persecution as in getting beheaded, burned alive, shot, tortured. There is some kind of resistance in Poland. They have a bishop and were visited by Bp. Williamson, RIP. Again, if there’s a place for vowed religious, I don’t know. I do know from Bp. W. you’d have to be fluent in Polish to assist there. If I left out any stable institutes, please list them. 

This is just my opinion on the matter, but at present, there are very few places for single, Traditional Catholic men and women not pursue a religious vocation. Add the word “Resistance” to the description, it’s limited more, perhaps even more limited than finding a suitable spouse.  Paucity of o both spouses and religious vocations may indicate God wills more people remain single in the world. Properly speaking, such status has never been a “vocation” or a “state of life” recognized by the Church. Those who who find themselves in such a position have been viewed by the Church and her members, as unfortunates, deprived by others, self, or life circuмstances to the sidelines. They’ve been made to feel like the Little League child left on the bench, game after game. For reasons known or, worse, unknown, whom the coach never calls to bat or to play any position, not even to be a bat boy. There he sits year after year until he ages out of eligibility. He gets no explanation from his coaches and after awhile, goes unnoticed or is the subject of rude jokes and cruel comments of his teammates. When he reaches the maximum age, he quits coming and few, if any notice his absence. The few who do notice do not inquire after him. He correctly concludes nobody known to him cares. He’s quickly forgotten as if he never existed. 
Life goes on in much the same way. He graduates high school with a 2.8 GPA. Works at various jobs, retires, moves in with his mother, cares for her until her death, lives another 14 years and is found dead by police after a call from neighbors who noticed his overflowing mailbox. He never married, left no kin, but a will was found. Everything was left to a law firm. According to instructions, sale of the house covered a Christian burial, the furnishings paid the lawyer, sale of his mother’s jewelry went to a small number of worthy charities, and his remaining assets for a dozen boys to play Little League.
