the message was sexual in nature, OP was able to understand the gist of it.
Although there was a lively discussion about his nationality being relevant, in that in certain cultures it is common for men to behave like this, there was a heck of a lot more to your last thread than a bunch of women blaming him for being foreign and therefore guilty. 
If everything were fine and dandy with this guy, you would not have posted last week.
Nor in fact would you come and ask again for advice.
I know you are young, so perhaps this is not clear at all to you, and you are wiser than I was at your age, you are seeking opinion.
You know my thoughts, you can even discount them as me projecting.
But removing all my hang-ups/experience in the subject, the best advice anyone can give you is to see what happens.
Let him go.
Gather your thoughts, work out what YOU want. If he was committed to you there is no way one earth he would leave. No way in a million years.
It now doesn't matter about the message, that is immaterial, he has failed to deal with something that should have been a no-brainer if he were fully committed to you.
Again, let him move out, take time to get to know yourself again, enjoy your time as a woman, meet up with your old friends, get some fun into your life that is nothing to do with men or relationships. Find your self esteem, discover the woman you have become and learn to love her. be your own best friend and ensure that you can live as a single entity that doesn't need a man to exist.
