Congratulations on embracing your Catholic faith! There is rejoicing in heaven! :extrahappy:
The only advice I have ever seen given about "missionary" dating/marriage is: don't.
It can seem like a nice idea, to dedicate your life and person in the hopes that someone will convert. But when you think about it, you are predicating your entire relationship/marriage on the hope that something fundamental about the other person will change. It's hard for me to imagine this creating the stability necessary to raise a holy family, as you rightly desire.
I would also discern the nature of your boyfriend's willingness to convert. Real conversion is not a matter of RCIA and baptism, it is a matter of one's honest beliefs. If you are called to marry, you would need a real Catholic as your husband. Is he really interested in Catholicism, or is he more interested in keeping you?
Now we here at CAF cannot know your situation like a counselor can, so don't take what we say on personal matters as the final word. However, we can offer good advice (many on here have experience to speak from) to be considered prayerfully.
God bless you and welcome home! :thumbsup:
