Came home to..

What would you think if after you woke up to your bf playing porn & jerking off next to you to the porn scene /category of a guy cheating on his girlfriend to coming home the next day to the back of an earring on your kitchen table (I don’t wear earrings), some kind of stiff -ish stain at the very edge of your bed, your perfume in a spot in your room you didn’t put it and a t shirt covered in cum in your shared closet?

Am I jumping to conclusions? He said he found the backing of the earring between the kitchen & living room & we just bought a house from college girls who have their ears pierced. We do have a 3 mo however the spot was in a weird spot on the bed so not really thinking that’s from him and well.. idk. I feel sick to my stomach. Posting anon so may not respond to responses. I’m just in shock..
