exquisitetobe - This is something that you've talked about off and on for some time now.
If I remember correctly you've had an opportunity offered for a promotion at work that would require you to relocate that you've turned down.
From my outside view there are a number of pros and cons about living where you do. Let's see how I do on the list:
cons - your ex is still very much in the picture as he is in the same geography and you encounter him far more than you would like and that causes you a lot of stress - you feel a bit trapped and isolated in your ability to form new relationships
pros - you are reasonably close to your kids - your daughter has an uninterrupted life - you love living in that part of the world surrounded by nature - you are in an area where your language and culture is common - you are in a (somewhat) reasonable distance to your parents and extended family
I do know that your kids have encouraged you to date and even suggested looking at options that are several hours away from where you are right now.
You are in a tough spot. You are a Mom. That is a lot of your identity. You feel that you have a responsibility to your children to support them and give them the best possible environment.
I can't advise you on the impact of moving on your D16. I really don't know. Have you talked to her about it? I know that your kids are as supportive of you as you are of them. I can certainly expect that if you uprooted her and moved to a Greek island to sell tacos that her grades would undoubtedly suffer. As would her relationships with her friends and especially boyfriend.
I do think that it's very healthy that you are thinking this through - but you are a very thoughtful woman ((exquisitetobe))
