Why would he cheat in my house?

I already dumped and blocked him. Nope I didn't catch them (I was at work) but my neighbors and a security guard told me he was seen bringing the woman in my house. Someone in my neighborhood even picture of them stepping out of my apartment and sitting on the outside staircase.

Cheating is already awful but if you're still going to do it, why on earth would anyone do it in their partner's house? Now I think I might have to arrange some things in my room. I don't even want to imagine everything that happened inside. Thinking about it gives me nausea.
