Family rivalry

Ok so last week my bf and I found out we're pregnant. My family are not to happy because I have 2 kids already and they would prefer us to have been married. I understand, but we been together for 3 years. His family on the other hand is excited and supportive. Now both sides of the family are talking about meeting up and stating their opinion. I know it won't be a good thing. Everybody is getting on my nerves and I just want to take a break from family. Today I feel like not talking to my bf and just be in my own zone, I'm moody and I don't want to be mean but I'm already upset because both sides are upset with each others opinion.
