I've been through all that you say (including getting blown off on my birthday and father's day) so trust me when I tell you this...you will be fine and there is life and love after this chapter you are going through now ends. You are simply moving through at your own pace and process the space between chapters.
One thing I would share with you that helped me was "stop grieving over what you lost and start living on what you've got left. You can make it on broken pieces."
