Would you convert to your partner's religion?

Imagine you meet someone who has a different belief from your own. In fact, you are spiritual, but not religious, you somehow have found your spiritual path, but now the person whom you regard as a potential future partner definitely wants you to convert to his/her religion. He/She can trade anything, is flexible about anything, except religion. You start studying that religion, you feel there is something deep about it, but you don’t know if you can really follow it, completely commit yourself to that path. And you know that if you just adopt that religion to marry him/her and finally you are not able to practise it well, he/she will be disappointed. Would you take the risk and still convert?
