Sister wanting attention
I never thought I would resort to talking to strangers on the Internet but I need other opinions. I have only been engaged about a month and I am still quite excited planning the venue as we are not getting married for two years. So far we have viewed two venues together, however my partner has to work so can't see the other venue with me. Both my parents are working so I asked my future mother in law to join me especially as we get on really well. I told all of this to my sister who has completely flipped saying that I'm leaving her out. I informed her that I wanted some time with my future mother in law and felt it was appropriate to involve her as they are paying for half of the wedding. I reassured my sisiter that I would love either see a different venue with her or I would take her back to one of our other options. Here is where she went nuts telling me that I was excluding her and wasn't thinking of her at all and didn't care about her feelings and how as my sister she should come before my future mother in law. I calmly told her I do care but still wanted to spend some time with my partners mother. The phone call eventually ended with her shouting profanity down the phone at whigh point I put down the phone. At this point I was angry but unsurprised as this was normal behaviour for her. Either way I rang my dad to apologise for the back lash he was going to experience (she lives at home), but was basically told that I was being unreasonable and should involve my sisiter more in the wedding planning. Again I have only been engaged a month other than venues and a quick look on pintrest I have done no planning. My question is am I in the wrong? I am quite upset as my dad is implying I am but my lovely partner says I have done nothing wrong. So which is it?
Hope you can help me with this as I am starting dreading planning if this is what the next two years is going to bring.
