Why does this Happen to Me EVERY TIME ??!!!!!

Why does this seem to Happen to Me Every Time I start to Truly TRUST SOMEONE ?!!!! As soon as I'm feeling completely comfortable with Them, and completely secure, then They go and do something like this !!!!!! DISAPPEARING WITHOUT EVEN ONE WORD OF GOODBYE !!!!! Over the Last Couple of Months or so, I've been involved in a New Relationship with what seemed to be a Wonderful Guy. He seemed to be EVERYTHING that My Last Bf - the Abusive Bf - was NOT ! He made Me So Happy ! I felt so Happy, Safe, and Secure, with Him. He was Patient, Understanding, Compassionate, Kind, Caring, Loving, and Romantic, with Me. I had been wanting Someone like that in My Life for a Very Long Time. I Loved being in His Arms, and just spending Precious Moments with Him was Heaven. He Never expressed anything Other than Complete Adoration towards Me. He was Always saying how Special I was to Him, and that I was His EVERYTHING... That I was His World ! He was Always telling Me how He Loved Me Very Much !!!!! So He gave Me NO REASON to think that ANYTHING was Wrong between Him and I. In Fact, it was HIS IDEA to Move in with Me this Weekend ! He said He was going to Call Me around 12 Noon Friday 3/6, and then He'd come Over with His Things, and start Moving in with Me ! That was the PLAN. But... FRIDAY came, and Time started to wear on with NO WORD from Him, until finally His Mom called Me, and Asked IF I had heard from Him !!!! I told Her that I hadn't heard from Him, and She explained that the LAST TIME She saw Him was Thursday Night Very Late - around 1:30AM - when He told Her that He was going to McDonald's. HE NEVER CAME BACK ! In Fact He didn't even come Back for the Next Morning - Friday Morning - to drive His Mom to the Bus Stop so She could go to Work ! She ended up having to Call OUT from Work Friday because of it ! Now it's SUNDAY NIGHT - 3/8/09 ABOUT 7:30 PM - and I STILL haven't heard ONE WORD from Him, and I assume that His Mom & Sister haven't heard a Word from Him Either since We had agreed to Let Each Other know as soon as We heard anything from Him. I wish He would AT LEAST contact His MOM & SISTER to let Them know that He's OKAY ! That's the Least that He could do, since They put Him up for a long while when He had No Other Place to Go. I would appreciate a Word from Him as well, but I would understand IF He contacted His Mom and Sister first. Is it Selfish of Me to HATE THIS ???? Is it Selfish of Me to HATE that He's Putting Me through This, after He Led Me to Believe in HIM ???? He led Me to Believe that He was Trustworthy, and that His LOVE for Me was TRUE.... But NOW I can't help wondering if ALL of it was just a HUGE BUNCH OF LIES !!!!! What else can I think ? Am I so UN-LOVABLE ?! Am I so UN-Worthy of having the Kind of LOVE that STAYS ?! HOW can You tell the " GOOD GUYS ", from the " BAD GUYS ", when They HIDE Their True Natures so DAMN WELL !?!?!? I was SO SURE that this Guy was a ' GOOD GUY '.... I had No Doubt. I wish I had KEPT the Walls UP around My Heart a Little Longer than I did with Him.... then Maybe His Disappearing Now wouldn't HURT so DAMN MUCH !
