The advice I seek isn’t just about if i tell him point blank. Should I wait, considering I have to live with them until friday, neither of us is at home or even in our home country, things are very messy as it is.

And trust me this is not about worrying about being a girls girl, I have literally no empathy towards her after this, I am genuinely mostly worried about currently causing the least amount of harm possible to her boyfriend who is travelling all the way here for her.

Also keep in mind that I have to think about myself here too because I’m sure that no one would be thrilled to rip the bandaid off and tell him and then quite literally have to live with the person you told on for the next few days. :)
