Feeling alone. 😢

I have the most highest gut feeling that my baby's father is cheating on me and i don't know how i can confront him about it 😭 when i ask to see his phone he just say "why?" and then that just hurt me so bad i don't know why 😭 i just want to know the truth, because i wanna know the reason why he would do such a thing 😭 and to know that he has a kik, tinder and other dating sites and worst thing he has a porn account on one of porn site 😭 it just torn me apart 😭💔
