How do you deal w the paranoia of your s/o cheating all the time? Like I’m constantly convinced he’s cheating, no matter what and it’s for literally the smallest things like him taking too long on his phone in the bathroom, or if he takes his phone with him to get water or smoke.. it’s getting really bad and I keep spiralling more. I created a reality where he cheats all the time and he’s just trying to love me and be supportive.. 

How do I cope with this? Or change my mindset? Where do I start I feel so lost in this
