This again. Its getting so old.

Hmmm. You might be nice and all, but are you only considering girls that are super pretty/slender or a specific type?

I've heard lots of "nice guys" bemoan the lack of girls, but the only "girls " they're interested in are between 20 and 30 years old (even if the "nice guy" bemoaning us in his 40s!!) and have body/face beautiful.

Time to look at the whole package (looks balanced with personality, kindness and brains) - you might get a nice surprise..

1. Niceness doesn't always prevent heartbreak, and malice doesn't always precede it. Just because you are nice and they seem nice doesn't mean you're each other's Romance People™. Ask yourself if your heartbreak resulted from tangible cruel intent or good ol' incompatibility.

2. I mean this in the kindest way possible, but verbally advertising your feminist principles may be repelling the type of woke baes you're trying to attract. Sadly, it's not uncommon for misogynists to ingratiate themselves in women's lives/communities by aligning themselves with feminist causes (looking at you, Jian Ghomeshi), so ladies may be wary. If you're as down with feminism as you claim, show, don't tell.

Also, what Anonymous said.

I dunno OP, I'm a seriously nice human being to everyone, but especially to women I am pursuing. I have learned the hard way that I also showed the complete turnoff traits of being a push-over, a passive wimp and not a hint of alpha male in me when they're around (complete lack of manly upper body never scored well either). All the girls I ever pursued were darn nice but given the time they all eventually cooled off on me and went their ways - all my fault for being such a wuss and putting them way up on a pedestal.
I am dying to have just one more opportunity to have a woman be into me. I am going call out any bullshit that I hear, I am going to state my desires loud and clear, and above all I'm not going to fear being rejected ever again...fuck that! But I'll still be nice, it's just who I am.
Sorry OP, you sound like you've yet to delve into this issue in a deeper sense. So, you are you asking where are the nice girls (aka the ones who won't dump me because their niceness would prevent them from doing so?) I've been starved for a true love my entire life but the last thing I'd want would be a fraudulent relationship where someone is stringing me along just to be 'nice' (you can only fake loving so long). Cut the cord and dump my ass on the road as soon as you know it in your heart, please!!!
They lost interest in you OP...happens to everyone - it's the cycle of life. It just doesn't sound like you've learned anything usable from your heartbreaks. You gotta turn that hard-done-by feeling into a I-just-wasn't-good-enough attitude and try to be a better man on your next opportunity at love...just don't try to be perfect.

Ewwwwww dude. Jussssst ewwwwwwwwwww.

Go buy a journal holy smokes.
;-)

.....just sayin'. So many people use that "where have all the nice guys / girls gone?" thing! Seriously, does anyone even consider that possibly its they that are the problem? Or, maybe, like someone else pointed out, it's simple incombatibility. The dating scene now is also so competitive since the Internet opens up an entire world of other options to people, so many people simply seem to have lost the ability to make any real commitment. So easy to assume there's "perfect" mate just around the corner, right? Anyway, try not to judge them so much, try to make sure you're being honest with yourself about what you're doing that may be part of the problem, and just keep on trying. Good luck !

"All women are this, and all women are that, and it's totally their fault, and they are an evil, hurtful lot, and I'm just a nice guy and a catch, and I am doing nothing wrong, and these fangs-bared women scare sweet men like myself away, and...

"I'm a feminist."

There is absolutely nothing shocking about the fact that the ladies want nothing to do with you. Oblivious, Arrogant, and Deluded: you are a one-man law firm, pal.

sometimes it just doesn't work out...

Please. Men often complain that "women never go for the nice guy." But then you actually talk to these men who complain the most and find out they're not as nice as they say they are. Did you even read what you wrote?

"I've always been left heartbroken."

"Women have scared nice guys away."

"Ladies, come find me!

Me me me me me meeeeeee

You know what they say about nice guys.
