GKFv2,
I was reading through this thread and thought the female perspective might be in order lol. I'm going to start off with the hard part first. I know it sucks but most of us having been through rough times in relationships.
When women are into a guy I don't care if she's working 20 jobs SHE WILL CALL if she likes you. Not just women because I have similar conversations with some of my girlfriends and I say the same thing. If someone really likes you they will call, even if they have to call you from a bathroom stall or in the car on the way to work they will call. Now granted there is always exception to the rules but usually it's a safe bet that if they aren't calling they aren't interested.
Why would she lie to you? Not many women are going to flat out cut you down a guy and say "I don't dig you stop calling me". Because is anyone really ready for that level of honesty? It's not about deferring blame it's just the way things are because unless you've guys made some type of commitment to one another then she probably doesn't feel like she owes you an explanation.
I think 4949 said it which I wholly agree you have to go out there and experience things for yourself. Look just because a particular women doesn't like doesn't mean that you are in no way unattractive or unappealing to women. You just have to find your niche and relax a little. Go out there and have fun just be safe and respectful. I don't know how much this is a secret anymore but if you want to get a particular female friend interested in you just let her see you flirt with other women

. Sometimes it just takes her seeing you in another light and not just in the friend's aspect. Especially if she thinks she might lose you.
Women need to see you as confident, socially adept, and desirable. But remember there is a fine line between being a creep and being a suave type. That's why when there's a boundary respect it. If she's not making overtures or if you straight up tell her how you feel and she's not interested. Don't cross the boundaries of friendships because it will push her away not move closer. This makes me think of this one particular guy in my office. He's in his late 30's and maybe once a upon a time women flocked to him. But now he tries to hit on every women (keeping in mind he's married) and we absolutely cannot stand him. Don't be this guy either. Because I think he's genuinely clueless to the fact that none of the women find him remotely attractive. This leads me to my final piece of advice.
Be careful when asking your friends particularly males for advice. Women are usually seen as the bitter gender but believe me there are plenty of men out there who are very bitter and in turn have usually very low opinions of women in general. So almost all of the advice you get from these guys will only hurt you if you act on it.
Then you have the other type who swears that he has no problem meeting women and even lets you in on his "tips" but in reality women consider him only a slightly better version of a toy or we consider him a complete tool.
