Mother in law

I am kind of in a weird situation with my mother in law right now. A little back story. I married my high school sweetheart. Back in high school his mother wasn’t really a fan of me only because we are lds and my husband and I were dating before I was 16. And that isn’t allowed. I could tell she wasn’t very happy about it. She never really talked to me then and hardly does now. My mother in law doesn’t really make time for us. She’s always with her friends. And doesn’t care to see her grandson when we are with her. She gives him no attention. However she will cry and cry when we aren’t visiting and asks for us to come see her. But when we are with her she hides in her room and is on her phone. My mother in law doesn’t ever acknowledge me either. And I think it’s because I married her baby boy. He is her youngest. And when I tell you she is obsessed with my husband I literally mean weirdly obsessed. I have tried to be her friend, I send her nice messages. I gave her a goodie bag when she had gotten sick and a get well card and never got a thank you. Whenever she calls my husband she only asks about him. Like I don’t even exist. This past weekend all of my husbands siblings and us went to visit her and my father in law and she had said hi to everyone in the room and skipped me. And then like five minutes later was like oh and hi sally (I’m not going to say my name). Is this normal?? I’m really not trying to be dramatic. I know it’s hard on my husband because he loves his mom. But he also loves me. I don’t think I can handle this lady any longer. She is such a trigger for me. She doesn’t make me feel one but welcomed at all. Should I just suck it up for my family?? My husband would never say anything to her because he doesn’t want to hurt her feelings. We’ve had so many conversations about it and it’s come to the point where I don’t want to see her. She doesn’t want to get to know me in the slightest. I have tried to be her friend. It is so hard to get to know her. She doesn’t try with me. I have always wanted to have such a close relationship to my mother in law. But it’s is the exact opposite. What should I do?? Am I in the wrong? I honestly just don’t know what I did wrong if I am. Send help plzzzz!!!
