MY DAD IS A WHORE!?

My parents are already divorced so he isn't cheating on my mom BUT! He is cheating on his new girlfriends. Okay let me start from the beginning. I'm 2years old, my dad goes to his home country to visit his family by himself. He comes back nothing really happens so fast forward 11 years later my dad is living in a new complex, he's told me he is going to have a roommate. I'm fine with that I dont mind. His roommate moves in. Its a lady and her son. The son is 10. Im 13 at the time. His birthday is august, mine is in march. My dad visited his home country in november. Do the math. the kid was also born in my dads home country. This kids mom also moved here and is dating my dad, but doesn't live with my dad, but a different lady lives with my dad but is also dating him. I think hes also dating his other coworker but I dont know I need to do more deep diving.

I think all his girlfriends know about it too.
