Am I the crazy one?!?

I'm 30. My husband and I met when I was 14. Ive been close with his family since then. Especially his sister. When my husband and I were still dating we were on again, off again, but I always maintained a relatively close relationship with my now sister in law.

My SIL has not has the easiest of lives. She had a teenage pregnancy that was very hard on the family. Shes picked man after man that just wanted some tail. She has a big heart but she was emotionally abused by her bipolar mother all her life. So shes a bit emotionally stunted. Shes horrible at empathy. I can't even blame her really. Her mother is without a doubt the most manipulative psychopath Ive ever met.

In the past year, my SIL finally found the perfect man for her. I mean like actual cupid perfect match for her. I love him for her. Hes great with her kid, he encourages her constantly. Just outstanding guy. Genuinely good guy.

They decided to have a destination wedding. I had just found out I was pregnant with my 2nd baby and was scared about money and travelling. So I told her we couldn't afford to be in the wedding but we would definitely be there. A few weeks later she told us that they're expecting a baby too. I was so happy for them! We had a lot of fun talking about baby stuff and deals from stores. But she started to talk less.

I thought maybe it was the stress of planning a destination wedding and being pregnant? I found out through my BIL that she was mad we couldnt spend more money to be in her wedding. The trip alone cost us $1000. She wanted bridesmaids dresses that were $350, hair/makeup done only by her stylist $150. She also wanted my husband and our firstborn in the wedding. Tux rentals $250 each. I was so upset that she had no idea this might be a stretch for anybody's wallet. But I wanted to wait for the appropriate time to say something so I didn't start a fight right before her wedding.

Then she had her baby. I thought we were ok enough then but thats when she completely disappeared. I called, text, stopped by, fb. Nothing. No response. Or at least very flimsy responses. Then her wedding happened. She looked at us said hi, then left to talk to others. Its her wedding and shes perfectly entitled to that but there were only maybe 20 people at the wedding including us and were a close family. It was deliberate to ignore us.

Weeks later she text me out of the blue, "are you mad at us?" So I responded very respectfully with "yes, weve been hurt. Were a close family and you disappeared." No response for months. Then she text back. "We'd like to meet to make things right". I told them that we were a bit angry and wanted to calm down so we could say the right things. No response.

So a family birthday is next week and were all supposed to get together. She called a family member and told them "due to the current climate theyre not going to make it". So I text her "this is a personal issue and has no bearing on our relationship with this person. We need to be there for the people we love. This is why theres a problem in the family." When something doesnt go her way she takes it out on everybody until she gets her way. Ive apologized to her for every fight shes had with her mom, brothers, friends. I have apologized. Its not even my place to apologize. I got tired of saying sorry for something I didnt do. No response.

So I found out I was pregnant. I told my husband, parents, grandparents I was pregnant and then announced it on fb. She screenshots the post sends it to me and says, "this is the real problem in our family. I look forward to hearing the birth announcement on fb too. I dont think this relationship is fixable."

Of course I immediately get pissed. I'm moody after all. I just got so mad I said "you can't disappear and then get mad when people dont include you" she told me I was a liar even though she hasn't contacted me for anything other than to decline RSVP for birthday/holiday parties. I have only seen my nephew twice. When he was born and at her wedding. Now she says I'm crazy.

I feel crazy. Like Ive missed the actual facts? Am I living in a different world then her? Am I the crazy one? I'm so angry!
