In laws🙄 am I crazy or what

Since getting with my husband his family hasn’t tried to have any kind of relationship with me. I am a shy/introverted person, I am not very good at small talk but when some one talks to me I react positively and try to have a good convo. When I work up the courage to start a convo with them I am ignored or looked at like I’m stupid and like I make no sense. They’ll say “what are you talking about?” And I mean it would be nothing to be confused about like, “The dinner was good, thank you!” I would get a reaction like that. It doesn’t help that my husband plays into it. Like yesterday at church my husband, his mom, his sister, and I was talking and I mustered up the courage to ask if they had anything to do. They all looked at me like I had said the most ridiculous thing “what?” I said again “Do y’all have anything to do, I just thought it would be nice for the kids to play together.” Response “no” then continued to talk like I wasn’t there, nothing out of the ordinary. I have done nothing to these people nor there son. They hated his ex for some good reasons but I’m nothing like her. I think they blame me for my husband not being stuck up there butts 24/7 since we got together but that was his choice. I even ask him if he wants to go to his family’s houses, he literally always says no. They have no reason not to like me. They even treat my child different than all the other grandkids, and there’s a lot of them. My husbands other child is treated just like the rest and he is the child of the ex they don’t like. I just don’t know!!! My husband says they like me but I don’t believe him in the least! IDK. The reason I made this post anyways was to ask if y’all think I should just give up trying. I know it will most likely cause issues in my marriage but dang it I’m done with his family!
