That must be a pain, people are silly though, they think cause you haven't been together long it won't work but sometimes it does, just as some marriages break up after years and some don't. My friend's parents "had to get married at 19 cause the were pg with my friend and they are still together now many years later.
Prove them wrong Celtic moon!! That'll show em.
BTW Congratulations, how wonderful that you are having a baby.
