I think my mom is cheating on my step-dad with her best friends husband? I’m not 100% sure but I saw some...odd texts on her phone. I was sitting in the car waiting for her, she had left her phone sitting in the cup holder and a text popped up from her best friends husband, I don’t remember exactly what it said but I was something along the lines of deleting texts and “no trace on my side”. Is that not weird? To me it sounded really weird, why would you need to delete texts? So a little bit later while she was doing something and I know this is total invasion of privacy but I could help myself, I went through her texts with him and looked like she deleted text messages too, that text he sent earlier was gone. I went up a bit further and the only weird text was from a couple weeks ago that said “u need some sexy pics” and no response then another one saying “sorry wrong #”. That’s extremely weird to me!!? I’m not sure if I should just forget about it or if I should ask her about it? I’m not a very confrontational person but this worries me, I also don’t know if I have enough “evidence” to accuse her of something so terrible! I need help, what do I do!?!
