Does your SO have a friend that you don’t really get along with?

My SO has a best friend since they were 5 and his wife and I, just don’t click. We’ve tried. Can anyone relate? How do you go about this?

Her and I tried to get along, we got VERY close but after I became pregnant she just doesn’t talk to me and doesn’t ask about me. Even though how much she helped me through TTC and supportive she was, she said I made her sad by being pregnant and she cried in my car about it...she hasn’t wanted kids for quite some time and neither does her husband. But talks to me about her friends pregnancy and how excited she is and all about her problems. But the moment I bring up my pregnancy she doesn’t reply until the next day. I began to just give up and distance myself.
