Psychic reading

Diana • Not TTC at the moment .
Do you guys believe in psychic readings ? 
My mom went to a psychic and since she is against my relationship -- wanted to see what our relationship has in store for us. 
The psychic says that my Partner is  a liar and is or will be unfaithful to me. 
Which doesn't make sense because he's pretty much always available for me and doesn't hide his phone . I even checked his Instagram and it was clean. 
He has lied to me like two years ago because he was insecure about things but then I ended it and ever since we got back together he has had a clean slate. 
Please help:/ I asked if he cheated on me and he said no but he was really upset that j asked him. 
I'm heartbroken and my thoughts are driving me crazy
