I (17F) recently found out my mom was cheating. Since April last year, I’ve already had a lot of doubts because of her suspicious behavior. At first, I kept quiet because I wasn’t sure if my guts were telling me the truth and I didn’t want to tell anyone else of my suspicions.

I gathered as much evidence as I could, ranging from places my mom allegedly went to [in which she would tell my father different reasons (e.g. work, team buildings), would go days without going home and not pick up her phone, she would then go home before dawn], facebook accounts of the guy I had suspicions on, emails, etc.

This is where I found out that she goes to another city almost 3 hours away just to see this man and hit it with him. To spare you all the details, I found a small paper containing the address of the hotel and connected it to the pictures she posted, as well as an email that was sent to her work office about her pregnancy. I was sure this was not my dad’s child.

Months of gathering later, I found the opportunity to tell my father about it. This had confirmed his suspicions as well. This caused a huge fight at home, and since then, things have gotten worse for everyone involved. My mother would buy him branded clothes and shoes, not even hesitating to loan hundreds and thousands for the man (she apparently inquired for a new motorcycle), all while we had to live off of cheap, thrifted clothing that costed not even half the price of the shoes she bought for him.

My father doesn’t want to end things with her because he wants to keep our family in tact. He suffered the same fate and doesn’t want us to experience what he did; Most of all, divorce isn’t legal in our country yet.

This all went down almost three months ago. Now, my mom demands that I apologize for “talking back” at her and “getting involved” in their issues. I didn’t want to, but my dad begged me to do it just to de-escalate things. I gave her a half-assed apology (cz who in their right mind would apologize for something that wasn’t their fault anyways) my mom mocked me and acted like I had no right to be upset or tired of the situation. Mind you, I’ve been carrying the burden on my own ever since I found out about her shit last year and I had to focus on my academics— now I have a new “responsibility” because of my newborn half-sister.

So, AITA for exposing the truth and refusing to fully accept blame?
