Many, many years ago (I'm an old dude, now), I dated a nonmember girl (I lived in Indiana then). Eventually, her parents got to her and she rejected me and the church. Ouch. Looking back, however, that all worked out well. I'm still faithful, and I've been married (sealed) for 20 years, now.
I was excited to read your follow-up. I'm excited that your family chose to at least listen with open minds and allow you your spiritual path rather than fight you like my old girlfriend's parents did.
Now that you're baptized, I encourage you to live the Gospel as best you can. Not only will that bring you joy, but it will also show your parents that this wasn't a choice you made simply for a boyfriend. Best to you!
