My folks were shocked and disappointed but extremely supportive. We had been together 5 years by then and were both 23. His folks however were not so great. DP told MIL first and asked her not to tell anyone as we wanted to do it ourselves so she promptly called his whole family to tell them. She didn't talk to me at all untill 2 months before DD was born
My FIL told my DP he thought it was a trap and I had done it on purpose to get his money lol. We had been living together for 4 years, the whole time DP was at uni and I was supporting both of us on pennies.
I know they were worried and concerned for him but it has put strain on my relationship with them. They are fantastic with DD and love her to bits but I can't let go of the fact that after so long they could think so little of me.
