Feel like I'm walking on eggshells with my SIL, she holds my past mistakes against me and keep wanting to "sit down and talk" for little things.

My sister in law is going through depression and a lot of things going on in her life.

I made a regrettable comment laughing about a comment my in law made about her infertility and I apologised PROFUSELY. She has said she has forgiven me.

Since then, I've moved into her home, I thought we've bonded so much. I have taken her out to eat to so many places, weve gone on walks together, cooked together, shared our problems about our in laws together and I have spoilt her and husband with endless gifts.

She has gotten mad at me again about an unintentional comment I made that since I moved in she hasn't had anyone over and she took it as me saying she has no friends. I sat down and talked to her about it and she brought up again my past mistakes and I again had to apologise.

Since then, I've been walking on eggshells around her, keeping my distance just to ensure I don't say anything insulting. I have lost that closeness and bond we shared because I feel like she hold grudges.

I've since moved out, and we had one instance where I didn't invite her to something when my siblings were visiting me in town. WEEKS later, she's upset again, brought up my past mistakes and wants us to sit down and talk.

Im honestly exhausted and feel like she's not mentally alright enoughto have mature talks if she's always going to bring up my past mistakes and hold grudges and not bring it up until weeks or months later. I said I feel like my efforts trying to get close to her are for nothing because she will always see me as a bad guy.

Our husbands want us to sit down and talk but I feel like her punching bag, this is our 4th/5th confrontation with me and no matter what I do, she'll always be upset. It's honestly hurtful also, to have my past brought up and just be someone's punching bag....

I'm not comfortable being her friend anymore but I don't want our husbands or anyone forcing me to have this talk with her.
