Why would my friends wife start doing weird things?

Long story short, my child hood friend got married a couple years ago and after the wedding they wanted me to come back to their home. I decliened becuase of things I had to do the next morning. The last time we actually talked in person was at the wedding/bar. Anyway today she took a screenshot of my snapstorys and not just one SS it was 2 back to back stories. I didn't ask but its very strange. She hasn't wished me happy birthday ever since the wedding either. I don't know it felt like she got pissed I didn't come back to her house after I don't know. She was asking me a lot of personal questions about my love life and what Im going to college for... her husband ( aka) my childhood friend was sorta shocked about how much she paid attention to my life... it was strange.. he wasn't even as informed as to what I was doing in my life than she was. Anyway Whats her motive? whats up with the random Screenshots? and they werent even pics of me. It was a screenshot of a vid im editing and the second story was a story of a store in NYC.
