It depends on how long distance it is. If it's just a b/f or g/f for the sake of having fun
and going out and being a good companion, then perhaps it's not worth it.

If there is plans for marriage or something then yea, distance shouldn't be an issue.

My g/f is about 40min away - 30miles so it's not that bad. Still a long distance phone
call but nothing a phone card couldn't solve and it's not that much either.
