You can pursue but in a light way and keep your options open!
It means feel free to go out on a dates with other guys until he fully commits to you - At this stage YOU ARE FREE and consider that there is no committed relationship yet!
At least until he comes and visits you or the other way round
You have no way of finding out what he's REALLY up to back home.
Words and promises are just that, words!... Until he really proves by ACTION that he really means being with you.
YOU ARE FREE! He does NOT own your life, ok?
