Converting to a religion other than the one you were brought up with is a hard decision. I'll give you the short version of my own experience.
I was brought up Protestant although my Dad never attended church with my mom and I. Going to church was sporadic to say the least. I've always felt close to God growing up and would always pray at night on my own. Religion was a touchy subject in my home because when my Dad's parents married, they eloped. Gma being Protestant and Gpa being Catholic, neither family thought the other was good enough since they weren't the "right" religion.
Well, to me going to church didn't matter much because I started to buy into what my Dad thought - that going to church didn't matter and that I could be close to God without organized religion in my life.
Now, my DH's family is religious and attended Mass every Sunday. I would go with them on occasion when I visited them. When we got married, we were married in a Protestant church, even though my DH is Catholic. I told him that I would not convert and that I liked my religion and he supported that 100%.
We had DD and we baptised her in the Catholic church. We "church shopped" until we found one we both liked and it happened to be Catholic. Still, I did not want to convert. Then DS was born and again, baptised in the Catholic church. One of the sisters spoke to me and said that if I was ever interested in converting, to speak with her.
Ultimately, I did convert (process takes about 8 months to a year). That was almost 4 years ago. DH was surprised and was happy that I was doing this for myself as well as my family. I never had any issues with being Protestant at all. In the area we live in, there are lots of Catholic churches. A Catholic church is the one we identified the most closely with. For me, I wanted to be the same religion as my children - to be able to take communion with them and to share the same religion as them. I do feel a strong sense of community with my church and we are very active in our Parish community. I feel more "whole" with my family and with God.
My family understands my decision and my mom is happy for me, although my Dad really could care less. They still accept me - even my Gma.
People convert for various reasons. Mine was brought about by my kids and it has brought me so much happiness. I hope it does the same for you. Good luck with your decision.
