She's gone from us

Am with my open minded wife for 17 yrs but at least last 4 yrs she lost to the net and her iphone .I bought Her an expensive camera and helped Her join a camera club but a year later she's spending more time online editing pics and excluding Herself from Us ( husband and 3 kids) and immersing herself in social media sites and now Her camera club. What to do? 9 year old has cut the bond and now highlights Her Mums flaws and social short comings . I can feel her pain being at home on her own etc but I did the same thing and built a network of friends which she since has torn down. She's obviously depressed but finds any excuse to turn all resolutions into problems. Only time She is happy is away from all Her family. What to do? all Her family means Her only sis and Mam

Yes there are marital and family issues and she is using online as a get away. Listen to what her problems are and address them one by one. She will come back.
