You might've intentionally friendzoned yourself my man. That's a horrible place to be. The thing about it is that you have to make her want you more than you want her, or at least an equal amount. You gave her everything in this situation whilst getting nothing. She made a mistake, and that mistake is you. You've got to get her to want to make that mistake over and over again

. If she's ignoring your calls you don't call again. One call is enough. If she ignores the first one she will ignore the second one and it's sever DLV to call again. If she /wasn't/ ignoring the first call then you'll here from her as soon as she gets done doing what she needs to do.
Also, for the future:
If a girl ignores one method of communication, don't try another. It makes you look "thirsty" and DLV's you substantially. Especially because whoever is with her will be like "
who the hell is that?" or something along those lines, and she'll reply with something like: "
this guy that just keeps calling me".
