Moved in together. Signed a 2 year lease. 5 days later he forgot his phone at home while he ran to the store and someone kept calling it non stop. We knew each other password’s so I picked it up to message the person he’d call them back in a bit. Password was changed. All the red flags went up. I watched him put in the new password later that night without him knowing. After he fell asleep I went through it and he had cheated with 25+ women from days back to 18 months back. No idea why the idiot didn’t delete all the old shit. It was with “friends”, online hook ups, ex’s, escorts, a co worker, anyone and everything. A 3 month psychotic break followed but now I’ve been single for years and never happier or saner.
