Tell him that, if it’s a matter that his wife just wants to be included ask yourself why you don’t want her there. Because your brother is married he sees her as an extension of him and rejecting her is rejecting him. If you really have no issue but just want sibling time offer a compromise of doing other things that includes your sister in law
She’s a really hard person to be around and she never lets him go anywhere by himself. She is always on top of him and even tried making out with him at my birthday party, we just want quality time with him alone every once and awhile, plus tickets are 120 each and now my sister has to pay for her too
Okay so your sister in law is just jealous in general, which means your brother barely has a say in it. You are gonna have to have a hard talk with both of them about how it’s perfectly fine for siblings only get together. Expect your brother to get mad or feel the need to defend her. Then say well I want us all to get along but sis in law needs to dial back demanding all the attention
