Gut feeling ?


I have a strong feeling that someone has lied to me. I don’t have a history of being paranoid and I am usually pretty trustful, but there are a few times when my instinct is telling me that something is sketchy and it’s usually right. How can I have peace about this piece of “bad news” whether it is true or not ? Trying to ignore or change my gut feeling just because I don’t like what it says (that someone I like is lying to me) doesn’t feel right. Believing it 100% doesn’t either. How can I acknowledge my “gut feeling” without driving myself crazy ?

UM 1
C : G canceled our plans for tonight
T : I have a very strong feeling that he lied to me about being sick
F : betrayed and angry at G
A : driving myself crazy wether or not that is true, trying to get more confirmation
R : unable to focus on my work

IM 1:
C : G canceled our plans for tonight
T : I am willing to give him the benefit of doubt
F : conflicted (because my gut feeling is so strong)
A : playing it cool while secretly resenting him
R : spent the whole evening thinking about it

UM 2 :
C : I have a gut feeling that he lied to me
T : My instinct is never wrong
F : sad that someone I like might have lied to me
A : withdrawing from the other person
R : the relationship with this person suffers

IM 2 :
C : I have a gut feeling that he lied to me
T : thinking this doesn’t do me any good
F : angry at myself for being so irrationnal, not allowing emotions
A : writing models
R : spending my evening trying to figure it out

I guess what my desired result is “stop obsessing about it, have a peaceful, productive night”. Can you help ? Thanks !
