Never expected to find this..

Was looking for a charger in my boyfriends car , getting ready for my son & I to go to an amusement park . & I couldn’t believe what I found . FOUND 2 condoms ! We don’t use that kind & I have ours at home . He obviously cheating cause he wouldn’t just accuse me of cheating or why I’m going thru his car !! Or blaming his friend for leaving them there . Why would his friend leave them there makes no sense !! I’m just overwhelmed. Don’t want to leave him cause my sons so attached but I’m done . I won’t won’t deal with it..
