I've just joined this forum and moved to London from Washington, D.C. a few months ago. Lots of great discussion in this "Spouse House" group - can't wait to dive in.
If there are any other women out there who can relate to being a "trailing spouse," and are looking to make some new friends, perhaps you'd like to join a meetup group that I just started, Expat Spouses in London. http://www.meetup.com/Expat-Spouses-in-London/
Let's connect, socialise, and be a support for one another as we settle into new lives in London. Make a new friend over coffee, a gallery visit, dinner, walking tour, and more. The group will be as active and vibrant as we make it, so take a chance, and come to an event.
First event will offer a real taste of London: afternoon tea at The Orangery on April 4.
Cheers, and hope to meet you!
