family help

**TL;DR;** : this is the sample summary. am i going the right way?

im '17 M' , my father '43 M' found out my mother '40 F' married for over 20 years, has been texting someone from 10 years kind of like an extra martial affair. my father is insanely angry(he has temper problems from the start) and has not been talking to her properly and they are acting to be normal just for me. yesterday while i wasnt home he was angry he caused chaos in home and broke multiple things and stormed off outside saying 'my home is being broken i wont see his home flourishing'. my parents both went to the guys home and idk what happened there. i want all of this either to go back to how it was by forgiving but not all this play and pretend. i have thought of forcing both of them to go on a vacation and sort things out and tell them not to come back until they sort it out. i have thought of convincing by threatening harm to myself but im not sure how all this will work out. is it okay to send them away like this?
