Still confused over here

Well its over a year later,,and I'd have to say my heart has never healed from this.  I have anxiety all the time and always getting dissappointed by him.  Are my expectations too high?  I have pondered that, but I have concluded they are not.  I am really not high mainteance, but I know I deserve to feel wanted.  I know in my gut this man does not really love me, maybe loves me alittle but not enough.  He loves to band-aid his lack of feelings with materialistic things.  He wants big ticket items all the time, gets it,, then the novelty wears off quickly and hes off wanting the next big ticket item.  Sometimes it feels that he senses he wants to leave me and to avoid that ,he wants materialistic things to make him happy so he won't leave.  Hes trying to fill his un-happiness.  When we argue and I say we should just give up on being together, he always says " please you would never do me such a favor"  .I am such a fool for wasting this much time. But if i leave I feel like I am a failure and gave up.
