So today I get a fb message from my stepsister (whom I didn't invite to the wedding) saying that she never wants to see me or speak to me again. This is her usual form of communication with me and I haven't seen her since my father's funeral 2 years ago. FI didn't want me to invite either of my sisters (half or step) because I don't talk to them and the only time they contact me is a once in a while hey on my fb wall. I have not talked to them on the phone in years or hung out with them in my entire life. I sent one sister an invite because we did talk every now and then up until a few months ago.
She also said that my other sister that I did invite wasn't coming and was never speaking to me again either. Im really upset about the whole thing. I have never been close to either of them, but is it really necessary to send me a fb message about it because you don't have my phone number?
Was it wrong for me not to invite her?
