Losing concentration!

I appreciate your concern about your brother! There are three main areas where people fail: money, women, and vices. Your brother falls under "women" category. By experience, it is doubly difficult to contain someone whose heart is madly in-love. I think the best thing you can do is to talk to him gently and discuss to him the advantages and disadvantages of the present situation. If he listens, you won your brother back. If he doesn't, pray for him! Of course you have to adjust to circumstances! Happy holidays.
