The one that got away help?

my boyfriend of six years and i broke up temporarily.i dated a local guy, i had always known vaguely!! We dated for two weeks.chemistry was intense and it felt 'right'.However, he finished it when i got back with my fellow.He told me it was my boyfriend or him. but every day now i see him in my work van, whether it be ping my house or at the local shop.He is always ogling at me!! it couldn't be a co-incidence. i really miss him.My relationship with my boyfriend is stale. what is going on here? what do i do?
