Can I ask you guys if it was any other faith that asks a lot of devotion and commitment i,e Jewish, muslim, hindu would you feel the same?
If you yourself had a strong religion not JWs and attended church giving a strong level of commitment to that God, would you give it up because your wife/husband said she/he didn't like it or the people and found it offensive?
Do we as humans have a right to tell another adult what they can and cannot worship? children are brought up in their parents faith but eventually they have to make a choice as adults for themselves but you as husbands/wifes do you have the right to make a spouse give up personal belief because you don't agree with it?
You may say "well it effects my life in a negative way" but would you then give your spouse a list of acceptable religions that you feel they can follow that wouldn't cause you to much hassle?
Someone having a strong faith in God is not unfaithfulness but it is something people will understand less and less these days, the concept that God is first is something most faiths do not in practise do anymore, if we have a faith now we bend it to our wishes not the other way round these days.
If my husband said to me "You can't be a JW because I don't like it " I would say "I'm sorry you don't like it" and try and make him feel loved around my being a witness but I would not give up my faith in Jehovah for him.
