Punky it seems you already have so many good advices. Go ahead and decide by yourself. If I put myself in your shoes, I will definetly leave him and move on. No need to keep lieing to yourself about him. You definetly know him much better and you can make a wise decision. Its one time pain but its worth it so go ahead. Good Luck exploring Qatar and remember there is always something better coming in the way.

Peace.
