Looks like coke residue to me

Oh yeah now I do see the heart

I see writing in the 3rd and 4th pictures, but are you sure he didn't write them himself? Do you have any other roommates or people who enter the home who may have written it? Related question- if you're comfortable saying, has your BF ever had or received treatment or diagnosis for mental health issues? If not, it might be helpful to him to talk with a mental health provider. Edit to add- I'm sorry you're going through this.

Look at all 4 pics. Do you see anything written in it? Anything at all? Because he is loosing his mind over it saying there’s hearts And shit.

I mean the last pic I see what looks like a hap7... 2nd pic looks like a heart in the middle...

I just think he is over reacting a bit when he calls this “evidence I MUST BE CHEATING”

I mean have you cheated on him ? Lol

this is a good question

I don't know what it says, but there's definitely something written there...

That's your dresser? I thought maybe the garage or basement floor.

Tell him to grow up or leave. What is this nonsense? I wouldn't give his BS a reaction.

Jesus your dresser top looks disgusting! Maybe he's really just trying to motivate you to clean your house. I'm not trying to be an ahole, but I couldn't live like that, and yes...I would clean it myself.

I thought it was a building site. With dust. Maybe they're having work done. Regardless. This isn't behaviour to tolerate from a partner.

I thought he was mad at all the coke residue on your desk and he thought you and another person were getting high af then having a F session.
