Do you think you ever get over your first love?

My first love and I were 16 & 17 when we met. I'm a year older than him. We spent so much time together. We'd stay at each other's houses. My parents LOVED him soooooo much. His mom, dad, brother, sister, and neices all loved me. His neices would call me "Aunt ___." We were together while I did my basics at community college and he finished his senior year. I went to prom with him. He decided to join the national guard. I went with him when he talked to the recruiter. He went to meps and swore in. I remember the first time he went to drill, and he had personal time to talk to me, he was so excited. We were so in love, and amazing together. We had two major fights, and mostly got along. I feel like we were perfect together. A few months before he left for basic training, he decided he didn't want to be with me anymore. Less than a week later, he had a new girlfriend. Summer came and I knew it was the day he left for basic training. I wanted to write him and tell him good luck, but I didn't. A few days later, I checked my laptop after doing a test for college. I had a message from him saying "hey this is random but I'm bored and at reception and was wondering how you've been." So we talked and talked. He wrote me letters and I wrote him back. we stopped talking because his girlfriend found out he was talking to me and they broke up. They ended up back together. Last thing I heard of him, he moved out of state 5 hours away to get a job. Well, I'm 21 now and I met an awesome guy. We got married. I'm super in love with him. But yesterday I went to our only grocery store (small town problems) and there he was. Working, pushing shopping carts in. He saw me and quickly looked away. He kept coming back by and looking over at me. As I was walking out, he was coming in. He said "hi," and looked down quickly. I said "hi," back. And he let me by him. It was so awkward. Today, my dad went to buy a part for my truck, and we went to the auto store. I sat in the car. And there he was. He pulled up and walked in. He saw me and was wide eyed. He talked to my dad inside, just like always. I haven't seen him in two years so it was just weird and awkward. He must have moved back since he has a job here now. Seeing him just brought everything back. Even though I'm happily married, it still just came back. Do you think you ever get over your first love? Should I have felt everything come back when I saw him? Or is that bad? Just all the memories hit me hard.
