If new scenery is needed then by all means indulge!...But wherever you go, make sure that the scenery isn't all that needs changing. The people that we choose in our lives are no accident. When I began to notice that same trend in my own life (feeling used and abused), I had to ask myself why I had chosen these folks to start with....and I had to finally acknowledge that I pretty much got what I asked for.....
(not what I deserved, mind you...but what I asked for) Best of luck wherever you land!
