Its sad that you feel lonely.
Don't be.
Shift your focus in life from finding a partner to other things, like your academics, your career, your fitness. You'll find when you shift your focus from relationships, relationships shift their focus to you. You'll find more people being attracted to you.
Its sad that we live in a society where men are put in postions that expose them to rejection whilst women are protected from this sort of thing. Thats not right. I think this hurts men a lot. It puts them down. It needs to change. I think both women and men need to share this burden together.
In regard to your issue, you might want to consider looking for relationships in places other than nightclubs. Nightclubs are not a place where people tend to generally find good relationships. They're loud, full of people that are drugged up and intoxicated. Its not a place you go to find healthy relationships.
Let me tell you a secret that no women would ever share with you that will help improve your prospects with women. The more attention you give women the less they become attracted to you. Give them less attention and they will work harder for your attention. Attention is a very affective currency among women. When we do not have enough of it we want more so we work for more and when we do get a lot of it we become jaded and disinterested. The second thing you need to note is that women want success and strength in men. The more successful you are, the wealthier you are the more attractive you are to women. You must work to achieve these gaols. If you study Medicine, drive a BMW and are buff you are going to have better prospects with women than if you were say a cashier at tescos that travels to and from work everyday using the public transport service. Also, the more dominant you are in society and in your social characteristics the more attarctive you will be to women.
Its not just guys that struggle finding a partner, women struggle too. There are lots of women in your position as well.
Feminism does seem to be significantly populated by unattrractive individuals more so on the inside than on the outside. They do kind of, a lot of them, have issues with aggression and entitlement. Just avoid them the best you can.
