<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was on my dad's phone, he had asked me yo set him up an email for him. But while on chrome I saw a tab on backpage.com of a woman looking for a man and on his search history were searches for backpage and craigslists.It is pretty clear why he wants an email now, rather than before. 

I have his password, im 16 and have no idead who yo confront and what to do. Mom is home so I cant really confront my dad alone till Saturday which is when dad is home. I was planning on cornering my dad on Saturday to beg him to talk about it with my mother and take marriage counseling but im afraid the damage will be done by then.Dad and mom seem pretty happy together and dont want to break that. Im torn apart and have no idea what to do.

It is almost guranteed they will divorce if my mother finds out. My aunt and uncle (both from my mom's side) have divorce their spouses for cheating. My whole family will be hurt financially and emotionallt. Especially my 10 year old brother and 13 year old sister. 

What should I do?
<bot>: Saw a tab on dad's phone of a woman looking for men ad. Dont know how to deal with the situation without breaking up my parents' happy marriage
