The best thing you could do would be to stop thinking of yourself as a loser. You sound like you have some serious self esteem issues which you need to work out. One thing women don't like are guys that are very insecure about everything. I mean we all are insecure about something sometimes but calling yourself a loser is just beating up on yourself.
As for getting over ex g/f's well that's not a very easy thing to do. I had a experience somewhat similar to yours. I dated a girl who came from a upper middle class family who's mom and dad hated me simply because i came from a working class family and was poor and white. They of course wanted their daughter to not only date but marry a nice rich Arab guy from a "good family" whatever the fuck that means mind you. Talk about racial and class prejudice
. I swear to god i could hear her mom's voice frost right over everytime i called the house. Damn good thing i was never rude to them 8(
Anyway long story short i ended up getting sick as a dog from pneumonia when i was living with her and she tried to take advantage of me at my weakest moment. Instead of hitting her parents up for money (i don't blame her on this because to say they abused her would be a understatement) she hit me up right out of the blue for $750 in rent when i damn well knew that would have covered both our rent since we shared the house with 2 other people and the house was the most run down piece of shit Ive ever been in and that includes the crack houses Ive been in. I don't know where she got the idea i had that kind of money since i certainly didnt have it and neither did my parents. Unlike her $750 was a big deal in our household. Not to mention she used up alot of my opiate and benzo script i had and when i ran out and could barely breathe due to pneumonia she refused to share any of her precious morphine with me and even had the nerve to ask me for my last $20 saying i didn't need it anyway since i was so sick
. Needless to say that was the straw that broke the camels back and i was on the next flight home. I should have known it was not going to work out anyway as she had way too many problems for me to deal with and had a suicide attempt every second week ffs!
I blamed myself for the breakup for a good year afterwards. I remember about a month after the breakup just thinking about how it all went down and totally flipping out and downing a 12 pack of beer and smashing every finished bottle on my floor. I beat myself up with alcohol, benzo, opiate and coke binges and if self loathing and beating yourself up was a Olympic sport id have won a gold medal
. It took about a year or more and actually listening to a few very good friends that it was not all my fault that we broke up. I only saw the amount of selfishness she displayed along with total indifference to how i was after i sorta cleaned up abit and regained my sanity that i had lost.
So there is no magic formula for getting over someone. But you need to stop beating up on yourself and to actually realize your worth something. The rest will follow.
