I need to meet more people guys mostly, how do I do it? Any suggestions? Do I go up to them? Do I not? What are the limits?What works best for you? Please leave an answer

Start Dating Again , By Meeting Some One New , Go Out As Friends First , And Don't Push It , Take Your Time And The Date Will Turn Out Great , So Be Slow And Aware !

The process would vary greatly if your 14 or 40..

Maybe read this first?

Sleeping, you are only 15 years old and supposedly just broken up with a boyfriend... so maybe you ought to take it easy in the boys department and just lay low for a little while? Concentrate on your studies? Or hang with your girl friends? Or join a club of interest? There will lots of time for boys later, kiddo.

(Footnote: I frequently forget to do this too but it can really help to look at the other recent threads started as a bit of background)

I don't suggest approaching guys.

If you meet a guy who seems interested in you somehow, then you should probably give him some clues, the green light for him to approach you.
OR
If you really want to approach a guy, then you should say "hi", followed by small-talk... but beware not to seem too "needy" because they'll take advantage of you.

What kind of game are you playing, as today you post that you can't get rid of the b/f you have yet you want another? Get rid of this one first and chill till you can learn how to stand up for yourself or are you jackin' us around?
