Jocelyn • married, Mother of 2🩷💙
So I just got married two months ago and I been catholic all my life and my husband is Lutheran. We are not like so big on our religion. As for example we don't go to church every Sunday. But before we got married I told him that I wasn't going to convert in his religion and we catholic have lots of traditions that i still want to continue to follow. We did get married by a Lutheran pastor. And I do go to their church sometimes and he will be coming to mine on Sunday for the first time. 
Did any of you convert? Or stayed in your religion? How did things work for you if you both are different religion? What about if you have children. Did anything changed?
