I had a boyfriend once who was so mean he wouldn't even put the air con on in the car because of the slight bit of extra fuel it would burn. He once took me out for MY birthday but I had to pay for it. He kept giving me "gifts" that were clearly either tatty old things he no longer wanted (an ex's old straw hat with a hole in it, for example - I kid you not), or that he'd paid pennies for in a charity store and that bore no relation to anything I might actually like... I could go on and on but I'm sure you can tell from those few examples that he put saving a few pennies far above keeping me as his girlfriend!
