Family baby dilemma!! HELP! 😭

Sarah
Hi, not sure if this is the correct place to post. Basically I'm 12 weeks today 👍 so so happy but I told all my family a few weeks ago and most were so supportive apart from my sister who I knew would be difficult to tell as she can be abit funny. 
Anyways, woke up this morning to a text from her explaining her feelings and that she is finding it difficult but she will support me but she is disappointed in my decisions.. I was so so happy that she was there for me that I text my OH with the good news and forwarded the text to him and he took it the wrong way and text her with a rude message saying how I deserve support and not to be put down. Now I've had family members calling me angry with him, (I didn't know he had text her till family called) yeah he was out of line as he misunderstood me when I text him and he said he wasn't gonna stand for her putting me down 😢 now all my family dislike him because he text her and now she has retracted what she said and wished me luck but don't want anything to do with me or the baby if my OH is around 😭😭 I'm so upset and I don't know what to do!! I've tried to apologise to her but she isn't having it and now everything is ruined and it feels like my fault.. Sorry it's long I just need advice 😭😭
