Feeling down in the dumps

Today my hubby went on his first every business trip out of town! It's the first time iv ever been left alone since we have been living together. He's only gone 3 days but what sucks is that the day before he gets back I leave for a 3 weeks visit out of the country to visit family. We haven't been as close lately, he's been working ALOT and has a side business he has to run and iv been looking forward to going away and spending time apart and for me to spend time with family but ever since I woke up this morning (he left at 5am) all I want to do is cry!
