Be a better girlfriend

I have been failing at this lately. Very badly. I have been emotional and needy and just generally very demanding. And I can see myself doing it, and I just can’t stop. Today I almost burst into tears in the middle of the street, just coz he made some call about me not having $2 in change. And then he had to spend the next 15 mins pulling me back together again.
Fact is I’m a bit scared. He seems so balanced and easy going all the time and he has good friends who he has fun with, and then theres me. And instead of giving him more reasons to love me, I’m slowly dissolving the relationship. I don’t know what to do about it.

This morning, like 15 minutes ago I really screwed up. BF got up early so we could spend so time together before he went to work for 12 hours. Yesterday I was complaining about how we should make more time for each other. Anyway, he tried to wake me up so we could have breakfast together etc and I didn’t want a bar of it. I just stayed in bed. Pretty darn selfish.
I really pissed him off. I want to make it up to him today, but I’m stumped as to what I can do. Helpful hints anyone?
I was thinking maybe get away for the weekend but his work stuffs that idea. Then watch his favourite movies while eating KFC, his favourite food. But I’m grasping at straws. He’ll probably see right through what I’m doing.
I feel so stupid, so selfish. He was trying so hard…

I went bowling(tenpin) with my boyfriend today. It was actually very enjoyable. He loves it, and it was a happy time for both of us. I think it could become something we do together coz I kinda like it too.

I’m struggling with this. I feel as if I haven’t got the chance to prove that I can be a better girlfriend. Tears running down my face as he tells me that he doesn’t want to break up but things can’t keep going the way they are, and that somethings got to give.
His statement is that he can not ‘fix’ me, only I can ‘fix’ me. Which I guess is correct but it sounds so horrible, so final.
He tells me that we are too shaky to go away on holidays together, and it really sounds like he’s given up.
Should I be preparing myself or working hard to show him that I care? basically he want to know what role he has to play in helping me through my issues, should he be the ‘knight in shining armor’ or the ‘shoulder to cry on’ or ‘the impartial listener who picks me up after?’ Also he wants me to stop being so dramatic. But I feel that these circumstances require emotion.
Because he doesn’t know these things he distances himself from me and that causes more drama.
I really don’t know what to do. How can I be a good girlfriend or even a good friend when I haven’t had the chance to.
Where do I go from here?
He’s coming over soon, I’ll probably give an update later.

My bf graduated today, I’m actually very proud of him. It was touch and go at one stage but he pulled through.
There was a ceremony and photos, and I’m really glad i went. I went with the intention of showing him that I care about what he does and what he is interested in – Computers.
I think sometimes I have to give a little back to him. He gives me so much that I rarely acknowledge and it’s not very fair for him.
So with our relationship hanging by a string, I’m glad I recognized that I needed to make an effort to save it.
