After marriage, do you really need to adopt the religion of your partner?

I was born Catholic and my husband is baptized as Catholic too…But in the long run they shifted to United Methodist. His parents wanted me to adopt their religion and forced me to give tithes. Do I really have to adopt their religion, or stick to mine? Sorry for the topic, it’s just that I am not used to be forced upon giving something coz I always wanted to give wholeheartedly without forcing and telling me the exact amount to give.
