Well, if you meet someone, get their b-day and we can do a compatibility. :)
a 4 year is not a great year to meet a love partner. It can be a good year to meet someone who helps you get organized and contributes to your bottom line, tho, so ... :)
All I can say about moving home is 4 years are a great year for retrenching and lowering expenses. Do what you can to save and ensure that you can keep up with your studies and progress. Progress and moving forward are your key words, prioritize that way, even if it means being a bit uncomfortable for awhile.
NEXT year/b-day you'll be in a 5 year, and 5 years are great for moving, dating, sensual pleasures, travel. So if you do move home chances are it will only be for a year, or at the most two so you can better afford to party. ;)
