I have problems with FIL... background is that I could not attend SIL wedding - myself and ds had norovirus so could not attend. My dh attended obviously. But since I didn't attend I have now been frozen out by sil. I'm not allowed in her home etc and see nil. She has not said this to myself but when I mention seeing fil my dh makes excuses. So I had a look at his phone and saw messages from SIL saying I am not invited in her home? What should I do?
