Long distance, love, what to do?

So i'm 19 i've been with my boyfriend for 3years & 5 months and due to personal reasons i had to move to the US. At the time we accorded that we didn't want to separate since we love eachother so much. So living here did make our relationship stumble and though i love him to pieces due to so much fighting decided to give eachother some space. But at the same time i started to like a boy from my neighborhood. I feel bad in my heart cus i really wanna be with my boyfriend but at the same time don't know if it's gonna work out with this long distance.
