When you first meet someone, character traits are not usually obvious (unless he is a complete moron or meathead). But as time goes on and you date someone, character traits are revealed. You understand how he handles and manages stress, his priorities and how he takes care of himself. You see how he interacts with his roommates and friends. You see how he treats his mom and sisters. You see the level of respect he has for them. Essentially, you understand someone much more when you meet his friends and family and see how he lives.
There are certain traits that are tolerable to a lesser extent, but if any of the traits listed below persist for longer than a few weeks, it is safe to say you are dating a loser and might want to consider moving onto the next guy. So, the sooner you can detect his red flags and unacceptable quirks, the sooner you'll be able to get rid of him and move on to someone who deserves to be with you.
Mr. Clinger - Quick expressions of love and passion are red flags. Be careful if he tells you he loves you after a month of dating. Get rid of him if he moves too quickly - before you have time to assess your own feelings. Guys who come on too fast and move too quickly are usually too immature to be with a girl. Moreover, they lose interest quickly. Healthy relationships take time to develop. Mature people understand what it takes to build a solid relationship. It's impossible to get to know someone that quickly.
Mr. Bad Temper - This guy is usually trouble because he has problems controlling anger. He frequently has temper tantrums. He has uncontrollable outbursts (very common with guys that take steroids). Yelling, cursing and throwing objects or punching walls serve to frighten you, followed by the quick reassurance that his temper will never get out of hand again. Guys with bad tempers should be avoided like the plague. Who knows, if he is having a bad day, he might swing at you even though he did not mean it and may end up seriously hurting you.
Mr. Put Down - This guy corrects your every move in both private and public. He corrects your speech and the way you walk. He tells you what you should wear and what you shouldn't. He tells you if you gained weight, even if it is only 2 pounds. He tells you your hair should be blonde when it is brown or vice versa. He criticizes you because your nail polish is chipped. He criticizes you for everything you do because it is never right. He attacks your self-esteem and self-confidence to make you feel worthless. This guy belittles you in front of your friends and his friends. Move on, this guy will only cause more harm than good because you will never be good enough for him. In fact, no one will ever be good enough for him.
Mr. Control - This guy will try to isolate you from your family and friends. He will try to instill fear and make you dependent on him for everything. He will try to manipulate you into believing that you can't survive without him. He wants to control you and all of your relationships. This guy will make you get rid of any male friendships. He gets jealous when you speak to your father or brother because the attention is no longer focused on him. If you don't answer the phone right away, he will question what you are doing, where you were, whom you were with, and will not ever trust you.
Mr. Cheap - It's one thing to be broke (because many college students are) but the guy who does have money and refuses to spend it on you, even to take you to dinner at the local diner is the guy to forget about because he is not going to change. There is a difference between being frugal and just plain cheap. It's good to be frugal because it will give him the power to do more things in the long run, but if he blatantly refuses to pay for anything, then dump him. You deserve to be spoiled from time to time. There is no reason why you should foot the bill every time you go somewhere. In addition, if he does have money, but refuses to spend it on you, it shows his true generosity, which is not much.
