Irene Pushed Clare????

In My opinion i do Feel maybe Irene did push Clare due to the fact that Clare was interfering too much with Irene and her life, family, kids, maids, or maybe even Irenes Husband. Irene just couldn't take it so she just had to do something even if was telling Clare Husband (Mr. Bellew) that she is Half African American. There is a good possiblity that Irene did push Clare out, Or Clare pushed herself out because Mr. Bellew knew about her secrets and didn't want to deal with him or Face the Truth. What surprises me though is that Irene was standing up for Mr. Bellew mostly defending him when people were accusing him of pushing Clare out the window, because Irene wasn't too fond of him so why bother defending him?
