Love / Semi-long distance relationship [3]

Hi there, I've been having an awesome year so far after getting together with my polish boyfriend that I've known for awhile. (I've been reading the forums on and off just to try to pick up any random polish words "NIE ROZUMIEN! NIE ROZUMIEN!" keke) I was just wondering if anyone ever has problems dealing with a long distance relationship and if so, how can you make it work out? I'm not exactly in one of those extreme halfway-around-the-world kinds, but my boyfriend lives in a different city and commutes to attend the educational institute we both are enrolled in. It has always been like this, and he's generally taken and showed up for courses every day and I saw him maybe a few times (now that it's summer, once) per week. However, in the fall, he's taking the time off to work to pay off tuition and I'm worried about how to keep the relationship strong for then.

...and apparently his mother would rather him date a Polish girl (from what I hear, she's extremely overprotective); so I'm extremely hesitant to meet her in the near future.. O_O Maybe if I were European, it wouldn't be as bad.. but.. I can't really help being asian.. D: Does anyone have any advice on getting over that cultural wall?
