People will discourage staying in a long distance relationship. Ignore them and give it chance.
Unless your relationship was already unstable before moving abroad, let it play out. Remember that the first 6 months are the worst. It becomes more tolerable as you adjust to the distance. Sometimes I even enjoy the space and freedom my LDR allows me to experience. I get the whole bed to myself and I never have to argue about what’s for dinner. The pros will never outweigh the cons, but try to be a glass-half-full kind of person.
