All the posts i have read are great advice as always in this forum.I just wanted to give an example form a 'real life' perspective that may help you to move on. I wasted 5 years of my life in total greiving relationships that i now see were totally  pointless, but i was too young to know otherwise.

My point is i know it sounds/may seem like it is very easy to say - but the worst thing you can do is greive something that really you have no idea would have been 'perfect' had it continued. I spent ages fantasising about perfect days we would have had etc etc...to wake up one day and realised how much of my time i had wasted and oppurtunuties meeting other people - bfs and otherwise. I know you probably feel like you cannot help your emotions- they are driving you to feel like you cant move one and let you psyche recognise that this guy is just immature and not in a space where a) he could apprecaite you as he should b) the relationship would not work out even if he wanted one - it sounds to me like the problem is just his total immaturity. Even if he manages to get the girl he wants- i bet you anyhting he will do the same thing to her within 6 months time (or at least eventually).

So take from my experience - i wasted 5 years of my life in the space you are in. And now i see that these men would have hurt me more had i have stayed in a relationship with them aka continued to take their bad treatment.I wish i had allowed the greiving, but simulatneously taken active steps to enjoy my life (which helps you move on)i.e a class you really like, anyhting in your spare time that teaches you an new skills and ideally to meet new people.It just subtly helps you focus your energies on better things and ensures you do not get caught up in the pain for too long (you dont have to make such a conscious effort).i hope none of this sounds too cliche- i remember when peopel said this stuff to me when i was going through it - i just thought 'same old' but i promise- it really does work. just take my omen of 5 years wastes and how much i wish i could get that time back.

Good luck.
Anyway

Hug first of all!
Please do yourself a favour and leave a guy who does not love you, care about you and does not spoil you.
Yu a vulnarable at the moment so do not make decisions in a hurry.  Be thankfull for that which is in your life which does make yu happy and wait for the good things to follow.
Yea sure shame on this guy, but he is making you sooo miserable.  That is not healthy for you.  You deserve to feel good about yourself.  And if it does not make you feel good about yu self you ignore it.
Hug Hug

While I completely sympathize with being in love with someone who doesn't love you..let us remember No one can make you feel anything but you.  This gentleman is not making her miserable..she is allowing it for herself...choosing to do so by staying, and thus there is a valuable lesson here for her to learn.  Or many valuable lessons.  My hope, prayer, and belief is that she will find them, discover the joy and love that is in her to do what is in her greatest good.

is happening exactly the same with me right now.. but there is not that we can do, so just move on and soon you will find someone.. everyone will,for sure

When things don't work out in a relationship it doesnt mean that you weren't good enough or that you failed.  Individually, you are both great people.  Together, maybe you just didn't compliment each other or bring out the best in each other.  This takes nothing away from either of you individually- absolutely nothing.  New doors can't open sometimes till old ones close- start getting excited about the future!!
Loving, gentle consolation to you, sweetheart.
