If that worries you, don't get baptize just be happy for your husband and allow him to worship his God. You can go to the meetings, assemblies, and conventions with him there's nothing wrong with that. The only concern is what if Jehovah's day comes tomorrow, net week, next month, next year, etc? How will you answer Jehovah's son Jesus?
You can take a study to learn what Jehovah requires of you and if you don't think you can be one of Jehovah's Witnesses then don't get baptize. Either way you still have to answer to Jehovah's son Jesus at Armageddon. Here's a famous quote as to whom you are going to serve.
(Joshua 24:14-15) “And now fear Jehovah and serve him in faultlessness and in truth, and remove the gods that YOUR forefathers served on the other side of the River and in Egypt, and serve Jehovah. 15 Now if it is bad in YOUR eyes to serve Jehovah, choose for yourselves today whom YOU will serve, whether the gods that YOUR forefathers who were on the other side of the River served or the gods of the Am′or‧ites in whose land YOU are dwelling. But as for me and my household, we shall serve Jehovah.”
And Proverbs teach us to love Jehovah and not forgetting his commandments.
Proverbs 4:4-7: And he would instruct me and say to me: “May your heart keep fast hold of my words. Keep my commandments and continue living. 5 Acquire wisdom, acquire understanding. Do not forget, and do not turn aside from the sayings of my mouth. 6 Do not leave it, and it will keep you. Love it, and it will safeguard you. 7 Wisdom is the prime thing. Acquire wisdom; and with all that you acquire, acquire understanding.
