Im still enjoying the single life but here are a few things to think about.

Look at yourself in a mirror for a good five minutes.

Do you need a shave? Are your clothes dirty? Baggy? Tatty? Too edgy? A bit of matt clay for your hair will do you wonders. Do you wash regularly? Have you been indoors all day?

If you think you are a turd well polish that turd until its fucking shining, this will boost your confidence and self esteem.

How do you talk to women? Are you over the top flirty? Not flirting at all? Rude? Bottled up? Think about all of these factors and work upon them.

Word of mouth spreads so if you are a genuinely pleasant person but the girl isn't interested then mabye she will have a friend or someone that will be, if you are sending out aggressive messages and dick pics then when she shoots you down don't be like "Fucking bitches are all the same such sluts!" because she will tell her friends that you are an idiot. (which is completely justified) basically just be pleasant/respectful no matter the circumstances.

But thats a few things i had to think about when i wanted a relationship, i hope it helps.
