he gets me so mad!!!

today rick went with his friend to a pick-a-part place. SUPPOSINGLY his friend was going to look for some parts for his car. they got home about 3 hours later. MR. RICK bought some stupid stuff from the pick-a-part. when his friend left ALL HELL broke loose! i had told rick that i wanted to get my hair done. so when his friend left he was like "aren't you gonna go get your hair done?" and i said "no, whatever money we have left, we need to spend it wisely like on the kids school stuff." and i got up from the sofa and i walked off to our bedroom. so then he called me back into the living room. he said "what can i do or say to make you happy?" and i told him,"you should know me by now, we've been married for 10 and a half yrs, you know that i am never happy. i am never happy with nothin', even you yourself have told me that before. so why do you even ask?" then he asked why i was so mad and i told him because he went and spent almost $80 on stuff that he doesn't even know if it works or not. he bought 3 used amps out of the back of a car and he also bought some other stupid tools and stuff. i was so pissed off for the reason that he purchased this stuff without even knowing if they work correctly. then i told him "this is not the first time you do this. you did the same thing when you went and bought those tables for the living room. and you've done other stuff that i don't even remember." by that time i was already screaming at him. i told him "i've never made the decision to by something big like that without asking you first. and why do you keep doing it to me? this is not the first time we've had this arguement." and he was like, "ok. i'll just sell the amps." and i told him "what if they don't even work? we're out $60, money that we've could've used on something else." he said "get the reciept for the tables and go get a refund." that got me even madder. i got up and i told him "we're through talking" he followed me into the bedroom, and he asked me why was i crying and why i was so upset. and i told him "how the hell are you going to tell me to go get a refund on something that i didn't have nothing to do with, the damn things are not even under my name. you've got some nerve." then he started talking about never doing it again, and he should've never told me to get the refund, and blah,blah,blah. so i ended up crying myself to sleep. i am still mad at him for purchasing that stuff. i mean, i couldn't even get my hair done. tell me, am i being selfish?
