AITAH for telling the truth about my best friend of 8 years

I (24F) have been friends with Liz (22F, fake name) since we were 14&16. I had just moved from out of state to a new school and we kind of bonded over traumatic home life/upbringing. We’ve been through the struggles of leaving our toxic families and starting our own adult lives through consistent support from one another.

Liz being 2 years younger than me, she didn’t move out until much later than I did. When she was 18, she got pregnant by a man she was dating who was much older than her. He had also previously dated her when he was a legal adult and she was 14. Regardless, they had their baby when she was 19 and while everyone was uncomfortable with the situation, we kept quiet because we knew she was being groomed, and all we could do was prepare to help her when she was ready to come to terms with that.

However, when she was literally 40 weeks pregnant (she gave birth at 41+ weeks) screenshots were posted online of her boyfriend talking VERY inappropriately to a 12 year old girl. As a victim of CSA I am unwilling to relay the messages here, but there was absolutely no questioning the nature of the conversation; it was very explicit. Boyfriend was in his mid 20s at the time for context.

When it came out that he was a pedophile, she “left” him and raised the baby alone. The baby is now three, and Liz has let her baby daddy come in and out of their lives as he pleases. She has hooked up with him multiple times over the last three years, and even had an abortion when she got pregnant with his child again. I turned a blind eye and tried to be supportive because I knew she was a victim and pushing her away would only do more harm than good.

It wasn’t until this past summer that things came to a head for me. When Liz moved out of her mom’s home, she called New Hope for Women and claimed her mother ab*sed her and was a safety risk to her child. I knew for a fact that this information wasn’t true, and it really bothered me, as New Hope had turned me away the winter before when I was trying to flee my physically ab*sive baby daddy with my 4 month old baby. The program told me they didn’t have resources available, so it felt like a slap in the face when I found out she was lying (and later admitted to doing so) to abuse the system and get put in a motel with her child for free. (I want to clarify that her mother was verbally ab*sive, but Liz and her brother both admitted it was never physical)

I STILL ignored this, tried to be supportive of her fresh start, and helped her move into the motel, and eventually into an apartment that New Hope paid for. (not to mention that when I moved a month after her she ghosted me the whole day and didn’t help or bother telling me she wasn’t coming. Not relevant to the story but worth noting)

After living in the apartment for a couple of months, she invited me over so our kids could play, and we could catch up over coffee.

During this meet up, she told me that she had been hooking up with her baby daddy again, who I thought she had been no contact with at this point. I expressed my concern because at this point we had had countless conversations where she realized and came to terms with him being a pedophile.

Reddit, I’m not even joking when I say, she looked me dead in my face and told me she was still hooking up with him because nobody could f*ck her the way he could. Apparently she’s into some really hardcore things that tinder hookups aren’t typically into, so she was willing to overlook him being a pedophile so she could have s*x. Meanwhile she has 11k followers on TikTok and posts about her journey as a single mom and paying for her apartment (that she doesn’t pay for), being a victim of domestic violence, being groomed etc.

I left her house that day so angry because I couldn’t understand how she had no moral issue with sleeping with the pedophile, just an issue with people knowing about it. We live in a really small town so I happen to be mutual friends with the sister of the 12-year-old who received the messages from Liz’s baby daddy. I texted the sister and told her everything, all of Liz’s lies, and everything about her baby daddy. I mainly just needed someone who understood the situation to hear what was going on so that I didn’t feel crazy. It makes me so angry for her son and I feel guilty for not being friends with her anymore because I can’t check in on him.

After I told the sister about what happened, she brought it to social media and basically spilled everything without using names, but again we live in a really small town so everybody knew who was being talked about.

Liz freaked out and deleted a bunch of her social media and refused to acknowledge any of the allegations. We haven’t really spoken since then and she trash talked me to all of my friends, saying that I was the only one who knew this information, but still claims that it was a lie. Thankfully, most of my friends understand that both of those things can’t be true, and they also know who she is as a person, so I’m not being accused of being a liar. I’m just wondering if I’m the asshole for kind of ruining her life, or is this just something that’s gonna blow over in two weeks?

Edit for clarity: Liz’s baby daddy has no custody of the child.
