So childish!!

My bf and I just announced we are pregnant, and although we are both excited and lots of people congratulated us, none of his friends seem happy about it. They didnt congratulate us, they found out last week and just said "wow" " thats crazy" i know for a fact NONE of his friends like me. I know it shouldn't bother me as much but i just wish his friends were more supportive, i wish they would put their feelings of me aside for the baby their friend ( my bf ) is having. All they do is talk crap about me and weve been together for some time now almost 5 years you'd think they would get over it.. Am i just overthinking or are they wrong?
