I, 29F, offered my friend 26M (aka A) my place when I was out of town for a week because they needed to use my washer/dryer. I told them they can have my spare key and to feel free to chill and crash. I live alone and they have roommates so I thought it would be nice to have their own space for a few days.

He agreed and said he could use the space to just do work and do his laundry. I went out of town on Monday and he came over shortly after. I Facetimed him that evening and asked him if he planned on having people over. He confirmed again he wasn't.

While heading back home, he asked me what time I planned on coming back and if I needed a ride. Told him I was covered but would be getting there that afternoon. When I got back home that Friday, he was there with his hookup buddy (aka B). Their stuff was everywhere and dishes were in the sink and B was doing their laundry.

I decided to let it go and just waited until they left.

Next morning, my property manager knocked on my door and told me my neighbors had complained to management about two strangers hooking up in the hot tub. (I don't think it was sex, just probably excessive PDA and heavy petting). I got a whole lecture about guest policy. For whatever reason, I had assumed B was only there on Friday to do laundry. Turns out B was there the entire time. Had arrived a couple hours before A did and had the place to themselves. Even the neighbors I'm close with in the building mentioned the PDA was excessive and made them uncomfortable. I'm actually embarrassed.

For context, A has complained about B not being respectful of his things and boundaries; they'd recently broken up over it. So while I know them, we're not close nor do I trust them in my space alone.

I did reach out to A saying this wasn't respectful or considerate, especially lying to me about the situation. He did apologize and told me he didn't think I'd mind because I knew B (again, I barely know them). I appreciate the apology but it doesn't sit right with me that I was lied to. If he truly thought I wouldn't mind, he wouldn't have lied. And he would have set the expectation that he just wanted to have a staycation with his hookup buddy and not just "work and do laundry".

Let it go or end this friendship? Worried it might be indicative of future problems down the line.

TLDR: gave my friend the house keys the week I was out of town. Agreed they'd be no uninvited guests. But turned it into a staycation for him and his hookup buddy.
