Male 18.5 yo , never in relationship ,no friends

since I was 13 I had the feeling I had no real friends or company. I had no peer that would put me 'above' of every other of his/her friends! now I'm 18.5 . I go out 2-3 times a week but most of the times I am the one who proposes others to go out. and when I do go out I don't like the people that are with me so much ! I know people I have fun with but we don't go out a lot !(they have other friends) I'm also in love with a very beautiful girl for 2 years. we went on a date only once and nothing happened.(I have told her to go out 10 times ) and I think of her every single day for hours. I'm desperate ,not because I have a bad life but because I want to live life exactly like I wish. I want to do preety much everything ! I'm also not in the mood to 'hit' other girls (although there are many which I like). as a result I have never been in a relationship ,or had sex. if all this was kinda confusing,my important problems are : 1) the love of my life doesnt want me,2) I want to have many 'short relationships' but I don't do anything to accomplish it 3) I need to have around me people I find exciting,and need them to find me exciting too !
