Samantha's Dating Thought-Is living apart the key to loving together?

These days, more and more couples who are in long-term relationships are choosing to live apart even though they could very easily choose to live together. Think of Carrie in Sex and the City 2 when she thinks about keeping her old apartment just in case she needs some time apart from Big when he starts to get on her nerves. Sure, moving in together can be a powerful way to strengthen your relationship, but if you take this big step before you are both ready, you could potentially harm the strong bond you share.  If you are thinking of moving in, start slow; keep some toiletries in his cabinet or put some clothes in his own drawer and vice versa. This way, you can see whether the two of you are comfortable sharing the same space. Or, you can think about living apart and seeing if having your own space is the key to making your relationship last. There is no rule that says that you have to be a part of every single thing your partner is doing.
So, what do you think? Is living apart the way to keep a relationship fresh and long-lasting?
