First off all, getting some weird vibes off of the fact he´s dating a 19 year old being 33 himself. Has he actually made clear he wants to start a family, like, right now? Why is he dating a 19 year old if he wants to start a family in the very near future? Of course you don't owe him anything. A baby is a lifetime commitment, not just something you 'owe' to your bf (who's also 14 years older) of 7 months who just happens to have hosted you in his house. People do things out of love for their loved ones, imagine having to pop out a baby every time anyone's being nice or accommodating. You don't owe anyone shit ever when it comes to getting pregnant and major life choices that influence YOUR life.
