You need to change your perspective on men, and like 411 suggested, don't jump from relationship to relationship. It is almost as if you are letting your overall opinion of men dictate the ones you chose... in other words, as you say, if all men are making you unhappy, you will inherently chose a man that makes you unhappy.

You also don't need to look that hard. When the time is right, an opportunity will present itself. With your attitude now, however, you may not take advantage of it... don't do that.

You must not only love with your heart, but your head as well.

Give yourself time to heal, and let the emotional dust settle, and learn to love yourself, and be happy with yourself.

Its also not a good idea to make a man the object of your whole life, and give it your all. You always save something for you, just to stay balanced and healthy.

Its about sharing, not just giving. Right now you just need time, and to stay busy building a life you enjoy, that makes you happy.
