Stepdad found out my moms cheating :/

(Gonna delete this) Little backstory, my dad who I loved very much died when I was 4 and my mom got remarried to who is now my stepdad. I have watched their marriage fall apart over the last year and I’ve seen some really bad fights that have left scars on my mind. Today at 3:50 AM, my stepdad went through my mom’s phone and found out she is cheating. The guy she is cheating on him with, I have already seen them together but my mom told me he was just a friend. My mom and stepdad had a big yelling contest and I walked in and my stepdad said “hey guess what (my name) your moms a hoe” and my mom went off on him about not talking like that to her son and they yelled it out. My stepdad left for work, and I just hugged my mom and told her I still love her and I forgive her. Despite being lied to and hurt in a way I never imagined would ever happen, I don’t see her any differently. I know Christ still loves her so I will too. This is really tough, but may the Lord turn this storm into a blessing. Amen.
