I can relate with the difference in culture as I am a Latino male and my W is Caucasian. The difference in culture could both be great at times, but present problems on others.
I am really sorry that you are here with us, but this is a great place, and a lot of great advice.
Latinos are very family oriented, does he have family around? Does he speak to them often? Hot blooded as well, which is why I can see why it escalated to physical quickly (never excusable). I myself struggle with control issues and controlling my emotions. Something I am working on now.
Can you give us what are some of the things your H has been expressing to you that he is unhappy with? As if he was telling you.
God Bless
