For inter-faith to work, a lot has to be discussed.

1. What are the goals in terms of religion for both parties? (separate religion? doing religious activities together? child up bringing? Super involved in activities?)

2. How strong is family influence on religion? (Seriously, if your parents don't support, its gonna be a really really tough road. Also how ready are you to deal with pressure from 'religious' friends, relatives, etc.)

3. If maintain separate religion, are both parties willing to learn and support each other? (It makes a lot of sense for you to still support your partner in their spiritual journey even if they are on a different path. You chose to marry anyway right?)

IMHO, stories about people forcing their partners to convert are there. But, there are also stories about people able to work it out while maintaining separate religions.
