Sara, I know you may feel sad about having a small family, but let me tell you that sometimes it`s simpler like that.
I have one sister and we are not close. My dh has 3 brothers, one has denied his parents. We haven`t seen him in 15 years. The second brother lives in Holland and the third is the only one we see only around the major holidays. Family reunions are never very easy or confortable. We visit for the children, only.
I have 31 cousins on my mother`s side, but we don`t really see each other unless we go to a wedding or a funeral.
To compensate, we have always been very envolved with our children`s school. We have made close friends there. Closer than family...
Remember that we can chose our friends. That`s a very positive advantage. We don`t chose our family...
I read somewhere, once that some people have a second family, their friends. Well, I hope I was of some encouragement to you, Sara.
