it still may bring you closer honey - having kids changes so many things (given it is so early for her she would yet to know that) and now you have the excuse of family get togethers etc. give it some time. this doesnt mean that wont happen - she is still in an old paradign of being a DINK... am sure she doesnt know what is around the corner. just be happy and there for her if/when she wants you... and the closeness will grow.
does she have sisters?
