SIL drama

LONG post! Ok, I’m making this post because I’m fed up with this “feud” with my SIL and I would love others’ opinions from the outside. disclaimer: I know this argument is completely silly!! And I hate that I have to take the time to even write about something SO ridiculous. But it’s unfortunately a legitimate problem in our friendship. Our husbands are brothers. We both have daughters, 7 weeks apart. They’ll be 2 years old soon. Her daughter is Ariana, mine is Arielle. My daughter is the younger one, but we weren’t talking when we were pregnant/our daughters were born so it was a coincidence that they had similar names. Well the girls were a year old last summer and we got them together a lot to play and everything was fine. I stopped talking to her after one night I brought my daughter to play and she got drunk, started saying she knows all these secrets about my husband but she’ll never tell me, showed me how she taught her son to steal from the candy store while we walked on the boardwalk, and a few more things happened but I was just like I don’t need this in my life. There’s always been this sort of competition (on her end, not mine) because her husband is a drug addict and can’t hold a job to support their family so they constantly move and live in not so nice places, where my husband is responsible and has a great job and we are blessed with a lot (not bragging! Just giving the facts). So we didn’t talk for a while. But I love her kids, they’re my niece and nephew and my godchildren, so a few months later when she posted a picture saying her daughter was watching the little mermaid movie, I decided it was a good opportunity to reach out and say “awe, Arielle loves this movie too!” Well since then it’s been NOTHING but drama. We got into a huge fight because she legitimately got mad that my daughter likes this movie and it’s supposed to be “her daughters special character”. Her actual words: “you force your daughter to like this movie because you saw my daughter likes it. Ariana likes it first! You force her to like it because it was your favorite character growing up” it was my favorite character yes, (and my SIL also said it was her favorite so that invalidates her argument right there) did I name my daughter because of that? No. My husband and I loved the name because it’s different. Plus it’s spelled differently. The thing that bothers me is that she’s saying I’m copying her and forcing my daughter to like it and that my daughter is going to have psychological problems, when my daughter literally begs to watch it and goes crazy dancing when its on, since the first time I put it on for her. She loves mermaids. Now with her daughter, she claims she loves it but any time I’ve seen her daughter she couldn’t care less about it. Yet every picture my SIL posts with her daughter, her daughter is wearing this mermaid, or holding the Ariel toy. Literally every single picture. And it’s so clear that it’s staged it’s not even funny. Her daughter looks miserable/confused. But yet she says I’m forcing my kid to like it and how my daughter will get made fun of because she has a mermaid name. Even though now she taught her daughter that her name is Ari and the mermaids name is Ari. She showed me her daughters summer wardrobe, I’m not kidding every single article of clothing has the mermaid on it. Over 30 outfits. She showed me she basically has a shrine of all this Little Mermaid stuff in her closet, plates, toys, dresses, little legos, etc. all this stuff she hoards but won’t let her daughter play with because she “throws it and ruins it”. (Duh) If you made it this far I hope you enjoyed the entertainment. I wish it didn’t bother me as much as it did. I KNOW it’s absolutely ridiculous especially with all the craziness in the world. I wish our daughters could play and our relationship could be normal. I wish this jealousy and competition didn’t exist. I wish I didn’t have to get worked up talking about a stupid mermaid in order to defend myself and my daughter. Ive tried to defend myself and make her realize she’s being irrational but she says “I won’t even read what you wrote, change the channel, oh you’re talking to yourself now, it’s obvious you went crazy when you saw me post my daughter likes it and you had to jump on it right away and force your daughter to like it right then and there” am I the crazy one to say, who thinks this way??? if I post one thing like my daughter dancing and singing to the movie, she bombards Facebook with a million pictures of her daughter with the mermaid. Feeling like I’m in the twilight zone haha. Any advice?? Please tell me I’m not the only one who has a family member that fights about such minuscule ridiculous stuff!
