Heres a bit of back story..
Been together 3 years have 1 young child together and rent a house together.
We have had our ups and down but no history of cheating worst ive seen is him looking up female celebrities online. Ive never ever found anything that would suggest hes cheated until today. I look on his phone ( i know i shouldnt but i can't help it. I wont be replying to any comments about this ) again never found anything on there until tonight i looked at his app history his latest searches are pof and tinder and his most recent deleted app is pof (plenty of fish) then further down the list is tinder. Hes had 3 phone changes since we met so i know its not an old search or old app. And also the 3rd thing he searched on the app store is the nectar card app which is something i know hes downloaded in last few months so this all just be recent.
I know i sound crazy and paranoid but i suppose if you keep looking you will eventually find something. Im not sure what to do. I know he will go crazy if i find out ive been on his phone.
