How long have you known him? Is this anger a new thing or are you just noticing it, or has he always been this way. If it is something new, maybe it's the stress of the wedding plans. If this anger was always there but it never bothered you till now, please do something right now before it's too late. Someone gave me this advice once which I didn't heed. You can't change someone. If there's a serious problem it will only get worse after the marriage, not better (usually). Don't think you can change something or hope for the best that things will be different. Most probably they won't. Maybe you can talk to a counselor together BEFORE you tie the knot and find out what's the problem. Good luck to you.
