Waw, she is in love, need advice/support II

[Bear007]

Long time I was too busy with school starting and lot of activities this brings until schedules aligns.

I am well, made some personal bests in running, working great @work, and accomplishing some minor personal goals, so yeah, life is good.

She has totally lost it. OM has gotten a girlfriend, and spent summer with her, his Instagram post is full of pictures of how he is having great time with new girlfriend.
She gained weight, quit the gym membership, started eating junk, depressed almost all the time. I tried talking to her (I am not total jerk) about how to help her, but we are getting nowhere.

D10 is starting to show signs of puberty rebellion, still childish, but I see lot of her mothers behavior in her, and also mine behavior, reflecting like mirror.
