Yes, and you have no idea how many others he is trying the same thing with. That is a real trial.
I won't go into this too much right now because it hits just a little too close to home and the other bro's and sis's have already expressed very good, encouraging thoughts.
However, I feel like it's important to bring out that we are not the ones that break up families! The refreshing truths we learn from God's word, the Bible, only benefit us and make us better spouses, siblings, children and parents. Learning the importance of showing love does not break down a family. It is Satan's world that breaks up families. His enticements like the ones you mentioned.
When ones like your wife leave, it is because of the lies Satan has spread. Of course, there have been many cases where spouses have returned after realizing that the truth actually benefited their marriage, so don't lose hope. You never know. What you do know is that if you leave the truth just to get her back, you will both lose out. She will be losing what is quite probably the best chance at her coming to know the truth and gaining everlasting life, your good example - and you will be losing a clean conscience, your hope and your relationship with the only one who can give you strength in times like these.
Remember Proverbs 3:5, 6 - "Trust in Jehovah with all your heart and do not lean upon your own understanding. In all your ways take notice of him, and he himself will make your paths straight."
When ones who have been in the truth at one time and then left the truth end up leaving and/or cheating on their witness spouse, it is usually because their spouse is simply a reminder of their conscience, even if the spouse doesn't say a word. They know what they are doing is wrong, and their spouse is a constant reminder of how far they have fallen.
What I have learned is that not everyone wants to change. Even when they know they are wrong, it is a choice that they make. And as dire a choice as we know it is, it is their choice to make. We are left with broken hearts now, but we can gain comfort from what Psalm 147:3 says about Jehovah:
"He is healing the brokenhearted ones,
And is binding up their painful spots."
Matthew 10:32-39 can be helpful when our family members and loved ones are trying to turn us away from Jehovah.
So can 1 Corinthians 10:13: "No temptation has taken you except what is common to men. But God is faithful, and he will not let you be tempted beyond what you can bear, but along with the temptation he will also make the way out in order for you to be able to endure it."
We know that no matter how excruciatingly painful what we have to endure is in this present system of things, our "tribulation is momentary and light" when compared to the endless blessings that lie before us. Let Jehovah be your strength right now, pour out your heart before him, and things will work out for the best in the end.
People's hearts change, for the worse sometimes but also for the better. Your wife may come around. In the meantime, don't give up. Like others have said, Jehovah will help you and he will bless you for your faithfulness.
Again, to answer your question - yes. "But take your stand against him, solid in the faith, knowing that the same things in the way of sufferings are being accomplished in the entire association of your brothers in the world." (1 Pet. 5:9)
