Accidentally liked your post rather than quoting it as my intention (sorry 'bout that) I'm not "likeing" your bad fortune by any means.
At least you know where you went wrong for next time.
You should try a more laid back approach (obvs). You're a naturally quiet person I imagine? Use that to your advantage, say little. The less you talk about yourself the more mysterious you appear, of course don't avoid talking about yourself, if she asks about you answer truthfully and genuinely keep a nice give and take leaning towards her giving you more information. Oh and actually listen usually guys don't and that's where they go wrong.
Self confidence is massively attractive, why do you think all the losers and d-bags get all the best looking girls? You don't need to be majorly attractive but if you're confident, relaxed about who you are and emotionally stable you will do far better than you ever thought you would, and your insecurities about dating will disappear after a while and you will no longer actually be needy and clingy.
That means lifestyle changes because I hate to say it, but the problem isn't women. Start with your wardrobe, dress what looks nice, not what's comfortable. Be well groomed. Stand up straight, and F***ing smile! Looking happy makes others happy, fact. Just don't push it, be relaxed and you're on your way.
In fairness, I have mood swings VERY often. I'm liking my bad fortune, it means more songs and it's kinda funny :P
Yeah, the thing is I know exactly what went wrong. What's funny is that she didn't tell me to **** off when I was being clingy, I noticed this and we kind of mutually ended it (even though she still kind of liked me) because I was being quite clingy, it was really weird... plus, she's said she doesn't want a guy to be like all obsessed with her and that. :P
The funny thing is that I might've used to be really quiet, but you couldn't be further from the truth now; at parties and social events, I'm usually the most social person around, going and talking to everyone and everything. The reason most of my things fail is because my brain can't understand subtle social cues which two people who are attracted to each other exhibit, and plus I don't usually get really clingy to a girl, only when I REALLY like them. Usually, I'm the dude who knows everyone and is friendly with everyone, so people never question why I don't get any, they just assume I do. :(
I agree completely with basically all the advice you've given me tbh. :P The thing is that I've done the majority of that already; I've changed my wardrobe out from what it was like when I was 15, I'm more groomed now, I smile a lot (people say I'm a very happy person these days...considering what I can be like when my mood swings hit that's quite weird xD), I actually practised my posture (gayyyyyy I know) and I'm much more self-confident than I was; I used to be the weird kid, now I'm the guy who knows everyone and I'm the lead singer of a band and basically improving as many aspects of my life as I can. The only problem I've got is the relaxing thing; I can't relax when I know I can't really get any, I'm friends with quite a lot of girls but I'm terrible with escalating anything which is why I'm permanently "friend-zoned", even though I think the term is cliché as hell. xD It's fine, though; what I'll probably do is just let it happen when it happens and just stop trying. Got more imporant things to think about now anyways (exams xDD)
tl;dr I agree with everything you're saying, but you have me pinned down as the wrong type of person. :P I just never usually feel so needy for a girl and I often get mood swings, so I come off as pretty pathetic a lot. xD
Thanks anyway though, that post actually reminded me of why I was improving my life like that before I hit that snag :)
