My girlfriend and I have been dating for about five years, and things have been serious (marriage, family, etc.) for the last four. However, she's Catholic and I'm Protestant. Although we're both Christians, the issues of marriage and children have come up since we're getting closer to the stage of engagement. 

Her family is very Catholic (generations) and many people have converted to Catholicism to get married. From a Catholic's standpoint, a marriage is considered valid when the two people getting married are both Catholic, so I'd have to convert. However, my family is against this and my ancestors have always been Protestant. In addition, I am not that willing to change my religion for her, but I'm slightly considering it because I don't want this relationship to end. 

We both knew this was a problem, but we chose to ignore it from the beginning. Now that we're getting closer, this is a much more realistic problem. The thing is neither of us are really that religious nor have we attended church in quite some time. But for our respective families, this is a pressing issue. 

Have any of you converted for your SO? Are any of you in successful interfaith relationships/marriages? What happens to the children?
<bot>: Families have conflicting religious backgrounds (Catholic & Protestant); must get married in our respective churches. Convert or break up or option c? Help!
