Salam sis, Anger problem is a major issue. If it bothers you now, it'll ruin you after the marriage. You don't sound like someone who's in love and looking forward to marry your fiancee. Normally people feel like that after 5 years of marriage when they start to settle and become 'best friends' with their spouse, but from your story... it seems he doesn't even care about what you think. If he chats with other girls and flirts with other girls behind your back before marriage he'll still continue this.... many men become worse in this area after marriage... trust your guts... but pray for guidance.... being single and happy is 100000000000000000000 times better than stuck in a marriage with a self centred man who doesn't give nothing about how you feel... (pardon the double negative) its all about communication, and you don't seem to have a good one going with him
