Hi-
In my experience, it’s been a very hard and rocky road. My husband and family are Evangelical Protestants, and even after 8 years together we really can’t get into too much depth about religion and doctrinal issues.
His family have the common misperceptions and really don’t care to come to the source to find out the truth. Unfortunately I don’t blame them because early in our courtship, at what rare times they did have questions, I didn’t have solid answers because I wasn’t very knowledgeable and lukewarm.
We tried to go to two services, but it’s very taxing to spend either all day Sunday at Church, unless you are a saint!, and/or spend every other Sunday fending off queries about why you worship statues and such.
Fortunately my husband, with the birth of our children, allowed me to put my foot down about raising the kids strictly Catholic and we now consider our shared home “Catholic” in belief and culture. Many other shared households aren’t as lucky.
Thanks be to God, my husband is showing interest in RCIA, attends Mass and goes through the ritual motions, maybe in time he’ll convert (please!) but I think he may be afraid of his family’s reaction.
I think his family has softened their attitude about Catholicism, at least to the point that they’ll concede at least one person can find truth while worshiping in the “Whore of Babylon”, but I keep apologetic material handy in discreet places for their visits.
My advice? Be prepared

for the possibility of a bumpy road ahead, especially since in my experience Church of Christ is pretty anti-Catholic, and really become knowledgeable about the Catholic faith, if you aren’t already.
Good luck.

I’m sure some people will tell you to avoid it, I’m not so sure that isn’t sage advice, but IMHO if my husband converts then it’s all worth it. That may not happen though, so don’t you expect change or conversion.
