I'm sure there are some very interesting Christian conferences, 
but obviously you attended yours after you were married, not leading up to it.
That's not true. Of the multiple conferences I've attended, there was one that I attended twice: once, before I was married and once afterward, both with the woman, who is now my wife.
I'm referring to divorce as Jesus defined it.. with "just-cause" being a very thin list. Accordingly, anyone who divorces outside the list is an adulterer, and anyone who marries such a person is also an adulterer. Adultery is one of the Big Ten no-nos whereas homosexuality isn't mentioned at all. Yet Churches are filled with all manner of adulterers, yet doesn't seem to warrant a blip, whereas homosexuality seems to bring people out in savage droves. Why is that? Because it's convenient and hypocritical.
Again, what Jesus did was shore up His stance on the issue, because the Jews adopted the nasty habit of frivously divorcing their wives, leaving them in dire straits. Add to that equation these men were trying to trip up Jesus, to get Him to make a mis-statement against the Law.
As for homosexuality, that falls under the adultery law. After all, adultery is having sex with someone OTHER THAN your spouse. And in all the issue of marriage, a spouse is clearly defined as someone of the OPPOSITE SEX. Again, as stated from Creation (and reiterated by Jesus in the NT),
"For this reason shall a man leave his father and mother and cleave to his WIFE (not male partner)
and the two shall be come one flesh". Plus, the (rather-enjoyable) order was given to "Be fruitful and multiply". Two dudes can't do that; and neither can two girls. When it comes to reproduction, it takes man and woman to get 'er done.
As far as where the fault for frivolous divorce lies... am I going to blame my heathen neighbor if I decide to murder someone, or steal something as well? No one forces anyone to sin.
Btw... you sound kind of liberal with your coddling counseling measures for would-be frivolous divorcees. You should throw the book at them!
My view is that counseling should be done to PREVENT this from occuring. You make an informed decision, when buying a car, a house, or investing in stock. Why shouldn't you do the same, when picking a wife/husband?
