Nope, not at all. My mom was over the moon at the opportunity I had to be here. She had been ill for most of my life and for various reasons (family obligations, poor health, poverty), her opportunities in life were quite limited when it had been her lifelong dream to travel. She was considerably disabled & in a nursing home already when I moved over, but she was thrilled with receiving the postcards I sent her from all over when DH & I travelled - she would tell the nursing home staff with enthusiasm & pride that she just couldn't believe that I was over here & able to do all that stuff, see all these places. And she knew, after a lot of struggles & unhappiness & disappointment I'd had in my earlier life, that I was finally happy & settled. Isn't that what parents most want for their children, after all? (My father was deceased since my childhood -- he hadn't been around for a very long time by the time I moved over here.)
I think my brothers (both several years older than me) were a little wary over my moving across the ocean for a guy -- they had seen me do all kinds of crazy things for love before when it didn't work out. But they wished me well all the same. And now, DH & I have been married for 8+ years, are very happy & settled -- my brothers & their families think the world of DH & see how well this life choice worked out for me. My life is so much better here than it ever was in the US. Ever since we left our parents' home, my brothers & I had always lived some distance away from each other anyway, as both my brothers had done military service & then settled several states away from where I lived.
Now that mom is gone - my relationship with my brothers is better than it ever has been! I think that's with us all being aware of the distance, the passing of time, and that we are all the (original) family that each other has left - with the passing years, we are making more effort than ever before to maintain & nourish our sibling relationships with each other.
