Is it normal for me to even be upset over this guy still?

Okay. so me and my ex dated for about 14 months....things were great until the last month. basically when we started dating he was jobless and no car. he was set to go into the marines. and decided to not do it last minute. so i helped him get a job since he didnt have a cell phone they would call mine. and i would refer them all to him. i also drove him to interviews and he didnt purchase a car until about 9 months of dating..so i did alot of driving. and i paid for most since he was broke and paying for junk car after junk car. well he turned 21 and im 20 so it was weird..i really didnt mind but his friends were pretty rude to me so i wasnt totally comfortable with him going out with them but whatever. i didnt say much. well then xmas came along and he bought me a promise ring that came in a zales box..turns out it was from kohls and he lied about. i wasnt mad about where he bought it just the fact he lied and imagine if i went to zales to get it sized! well we had been fighting after xmas bc i paid for my bday dinner and he had owed me around 500 bucks for his car stuff and tires i helped him buy when he short..and i was trying to find the nicest way to ask for some money back bc i had school tuition to pay..and he wanted a new tattoo. anyways he called me one day on the work phone and broke up with me..while i was in the middle of ringing up a customer..i was so devasted. he was terrible to me after that..treated me like a disease or as if i had done something so terrible..he said he couldnt take the pressure anymore..well i told him he needed to pay me back my money or i would just go right to his house and take MY tires off of his car if this is how it was. anyways...he had his friend pay me since he couldnt. so that was 6months ago..and i still find myself missing him..i feel like a total idiot for missing someone I paid for when we wanted to go to concerts or the beach or the city. but yet i still do. any suggestions on what i can do to move on..and i have that hopeless feeling that there arent any great guys out there..help!
