Going to a good movie (ever try going by yourself? it's awesome!), reading a good book (a great escape), having a nice dinner (with book!). I think it's a little easier for me fly solo after being single for a long time before getting married and having kids. But if it's new to you, try it! Don't let doing something by yourself stop you from doing it! We spend so much time as moms interacting (all day long it sometimes seems). Nice to give some time to just US.
