I had a very similar situation my freshman year of college. I got into the whole college scene, making new friends and everything, and didn't have as much time for my then-boyfriend anymore... especially since he was still in high school (I was a year older than him). I'd go through periods where I'd totally ignore him and then when I realized that I was effectively pushing him away, I'd suddenly start paying a lot more attention to him. It went back and forth like this for about 3 months, and then he finally got tired of it and dumped me for another girl. Looking back on it now, I know I really brought it on myself. But the bright side is, I started dating my best guy friend at the time shortly after my ex and I broke up and now we're engaged and very happy together! So look at it as being free to find Mr. Right
