It is very hard to find information online on Astrology and LDR.
In my opinion, ending up in an ldr could be an indication of finding your soulmate/twinflame, since your otherhalf simply isn’t always located in the same city as you are. Depending on where your 7th house ruler is positioned in your chart, it can be predicted whether you are meant to be with someone from a foreign country or not.
I suggest you checking your 7th house ruler for foreign spouse:
placed in 3rd (online meeting)
placed in 9th (foreign spouse, via travel, education in other countries)
placed in 12th house (other countries)
Or
Venus in 9th or 12th house
Jupiter in 7th house
The ruler of your 9th house placed in 7th house
The ruler of 12th house placed in 7th house
Conjunction / trine of 12th and 9th house ruler with 7th house ruler
Venus-Uranus aspect
