Should I say something about my ex bf/ex friend voluntarily going back to war?

The question is ... do you have feelings for him? (putting the financial and everything out of the way) do you love him? If you do, you should really talk through it with him and comfort him while you can. but if you dont love him and just feel like friends... then its really hard to change his mind...but do your very best to change his mind not to go to war.... sorry if this doesnt help....hope things work out. really do.
