Why do people have to be sneaky like that. If he wanted to break up he should have just told you to you face. Yes it might hurt but at least he was honest. However The only exception for someone sneaking out of a relationship is if you SO is abusive towards you

Relationships are complicated. It's entirely possible the guy thought this was his only option, and it very well may have been. Or he sucks as a person. Or maybe the truth is somewhere between. It's not something we will ever know.

You didn’t think there were problems before you left? A man cleaning for two days should cause alarm bells to go off!

Well just tell him you're 'Alone' at your vacation and have been doing nothing but taking showers in a really suspicious way.

He probably has been cleaning...cleaning up his new house

Better for it to end this way then to have his new girlfriend email you... (as my ex did to me)
