SIL is a bitch!!!

🚨FAMILY RANT-Please no negativity 🚨

So my husband has a sister who is almost 40 and has nothing to show for her life. She still lives at home and refuses to work and lives off of mommy and daddy. Her and my husband have never had a close relationship cause of their age difference (6 years), and it only got worse once he met me because I encouraged him to do something with his life. My SIL is a self entitled little bitch who thinks she can get whatever she wants and that she is the only person that matters. When we told her we were pregnant she locked herself in her room and cried all night. She showed no interest in me or the baby during my pregnancy and only pretended to care when he was born cause the family was around. Since she feels entitled to everything she expected to be made godmother cause she liked the title. We went with friends instead of family cause I wanted my best friend to be his godmother since she had supported me during my infertility struggle. My SIL was so pissed off she DIDNT EVEN COME TO HIS BAPTISM! I mean he is still your nephew you should come! She never wants to visit him and when we go over to his parents house she will look at him then go to her room. She shows no interest in my kid I get that but it still hurts. It hurts my husband to see friends siblings bonding as adults and he doesn't have that. And today to top it off I called her to wish her a happy birthday and we started talking about my sons first birthday and all of the sudden she tells me she's going away on a trip paid for by her mother that weekend of his first birthday. I haven't booked anything yet so I tell her I will gladly have his party another weekend cause we wanted it to be family only to which she replies "don't bother it's not like this is important or anything". I got so pissed I hung up the phone. This is my sons FIRST BIRTHDAY and I want it to be a small family even and my husbands only sister can't even be bothered to come?!? Even after I offer to switch days? I wanted to do it his weekend cause it's super bowl and I wanted a football themed party and I would change it for her and she doesn't care? I'm sorry this post is long but I needed to vent I think that's heartless to not care about your only nephews first birthday....I hope I'm not the only one.
