She faked a miscarriage???

i will spare you all the details… trust me it’s a LONG story i’ll try to keep this shortish 😅. My ex bestie (we’ll call her Marie) faked a miscarriage two weeks after i had my miscarriage. Before i get asked, i have proof that she faked it, i could post that but im not that petty. I didn’t want to believe she lied so i acted like nothing for months. A mutual friend (we’ll call her Amy) confided in me with issues she had with this friend We found lies on top or lies on top of LIESS. I would’ve preferred to talk this out in person with both of them but Amy preferred to do through text. it didn’t go well and basically Marie accused me of being a bad friend for telling Amy all the things she told me, keep in mind we wouldn’t never discovered her lies if we both kept this things to ourselves Anyways when Amy made the group chat she added their pastor which is my Aunt to be the mediator i guess???? idk why but she did. anyways we showed proof of every lie and she denied everything. A lot more happened after that but i don’t want this to be longer. Now my aunt talks shit about me and basically pinned half the family against me. Marie accused me of being a bad friend and blocked me off everything. Oh btw Marie is married to my cousin and Amy is also married to my cousin so they are sister in laws. and my aunt is the mom of both those cousins. I wish i could tell a story time video about this cuz there are SOO much details i left out. anyways i really just need an outside opinion…. was i in the wrong for telling my friend Amy everything Marie had done to me?? Also why would you ever fake having a miscarriage….. i wouldnt have ever talked about what she did to me if it wasn’t for all the proof about the stuff she did to amy… idk girl i just needed to vent i guess. most of my family doesn’t talk to me because if this. Im genuinely struggling with this, Marie is currently pregnant with baby #2 A girl 🩷. I would love to celebrate with her even with all that she did to me. Everyone in the family is constantly sharing her pregnancy with me as if i need to know everything🙃🙃. Also this month should have been the month i gave birth… I’m happy for her but i m also really struggling with trying to act like that strong women that doesn’t want more children when in fact i would die to have another and be pregnant right now. I’m having a hard time dealing with everyone around me growing their family and i’m possibly mourning the idea of not being able to conceive again. Anyways am i in the wrong for all this?? should i reach out to her and apologize or just forget about it ?? idk what to do.
