Excellent advice from Abigail, I like her suggestion for perspective in regards to your hubby.
I'm married to a Frenchman and we live in L.A. for now. I would love to move to (the South), of France in a few years. Even though I lived in Italy for a few years in my youth, (I'm now about to turn 53), spoke and still speak Italian very well, (I mention that in regards to speaking the tongue of the land) I want to search out any possible negatives to moving to France, for I can see mostly positive. My hubby's entire family is in France, and I have almost no family here. Also, there are no social programs for middle class aged people, nor good healthcare in the U.S. BTW my French is fluent. Nuf 'bout me.
I have an idea for you, not sure if it would work. I have a French friend about my age living in Toulouse and my parents-in-law who all sing in choral groups. One time when visiting Toulouse we went to hear my friend sing in an 800 year old little chapel. It was utterly charming and they sounded great! They did some classics as well as some Serge Gainsbourg, Jaques Dutronc, etc. If you don't want to join one of these groups, (actually I don't know how you'd even go about that), I'm sure you can ask around to see when and where a group might be performing, also I think it was free to be in the audience. After we heard our friend sing we milled about the yard and chatted. I think it might be a great way to make some new acquaintances and/or network in general. One thing I did read about making friends in France was that they take their time warming up to you for they take friendship very seriously, but once you make them... that's why I used the word 'acquaintance'.
I don't know how long you've lived in France, or where you live. I've been with my husband over 10 years, he's been in L.A. for 31, I was born here. I had French friends and had visited France long before I met Vincent, and he and I have visited France about 7 times together, for anywhere up to 1 month long stays. We get along very very well, and they are also super helpful and positive, unlike some stories I've heard of some French/Anglo relations. I'm just saying that everyone's experience and disposition is different. Or maybe it's a sort of disclaimer because I haven't actually lived there for any great period of time. I have heard about the bureaucracy, and the friendship thing, and I've felt that way even in my home town!
Also I think Abigail mentioned something about getting out to enjoy the good clime. To get out and walk about might be good for the soul. Eventually the people in your vicinity will get use to seeing you, and with a head-not or hello here and there, you might even meet someone who will make all the difference. But don't let'em smell your desperation, I've been there too and speak from experience, LOL
Best of luck, keep us apprised of your progress, I'd love to hear how things are going.
