stupid boyfriend... can you really be that selfesh?

So my day yesterday was just awful... I went with my boyfriend to his moms house to get a wood working book she bought him and 20 to work on this woodchest she gave him to redo.  The money was for the stain and seal.  I went home and was getting ready to go give plasma... he asked if I wanted his 20, and I said no your mom gave it to you, spend it on her woodchest, I will count change for gas to get me to plasma... so i did.. and I put 5 dollars in... I went to give plasma, he rode with so he could stop by lowes to get stuff to finish the cabinet... He knows it takes about an hour... Well since they couldnt take my plasma that day because my iron was too low, they said I had to wait 24 hours to come back.  I went outside and he was not there.. I called him and told him to come back because I was not able to donate today.  He got back and I asked if I could use 10 of that for gas and he wait till Thursday to get stuff for his mom.  He said he only had 5 dollars left cause he went across the road to go get a bottle of LTD.  I WENT MENTAL ON HIM... he didnt understand why I got so upset.  (or so he claimed)  I couldnt sleep at all lastnight.  My mind just kept going and going.  How in his right mind.. can he take the only cash we had and use it for alcohol?  REALLY?  who thinks like that?    I didnt speak the rest of the way home cause hes not suppose to even be driving anyways.  He kept making excuses, he apologized aobut counting his chickens before they were hatched... he needed a steady hand to work on the stain for the wood ... blah blah blah...  im just sick of it.. but I let him stay, because he has no where else to go.  Everyone around him is tired of it.  :(  and now hes stuck here.
