Does he have feelings for her?

Before being in a relo with me, a girl had apparently glanced over at my boyfriend and ever since he'd constantly stand at a distance and stare at her. This went on for almost 5 years but they never approached eachother due to cultural differences. Now all this ended 2 years ago and idc about his past, but he still goes to the extent of coding our pics to make sure that SHE doesn't find out he's in a relationship with me. (I only got to know all this through his friend but my boyfriend denies everything). Should I break up?
