Welcome to MarriageBuilders. You've stumbled into a forum that mainly deals with the issues of pregancies and children that have come from
affairs, although the Pregnancy/Child title doesn't really tell you that...
I'd suggest that you also post your story over on the
Emotional Needs forum---you'll get more people looking at the post over there.
On to your question. There's actually nothing 'sinful' about cohabitating with another person, either from a Christian or a Catholic perspective. On the other hand, there definitely is something sinful about sex outside of marriage, and it appears that you're already guilty on that count.
What I'm guessing that your BF's parents are upset about is the fact that you are pregant (and that the two of you are having premarital sex), and perhaps the question concerning whether you will be willing to raise the child in the Catholic faith. It might help to smooth things over if both you and your boyfriend were willing to listen to your future in-laws objections (without getting defensive), and perhaps then sit down with a parish priest to deal with the upcoming wedding, baptism, and the issues of your faith.
The bottom line is that when you two are married---you'll be responsible for each other. To sustain and grow your love for each other and your love for this child. However, the practical issue is that it will help to have both sets of parents supporting this marriage---and so I'd work very hard to see if you can't do so.
