Hopefully he comes to his senses and actually decides to grow up and start talking to me!
I hope for your sake, he never contacts you again. You seem to have a hard time seeing how this jerk keeps you around but never actually commits to you, he keeps coming in and out of your life, he last minute invites you to a NYE thing and then bails at the least little provocation.. to top it all off, he's out of your life yet again and acting like a 12 year old by not talking to you.
A man that wanted you, who actually respected you would want to be with you on NYE and he would make sure that he asked you well in advance, not the night before.
Close the door on this twat... Don't let him come back through under his terms while you wait with baited breath and hopefully, you'll rehab from him long enough to be able to not let him hoover you back in again.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
