My wife is in prison, and my daughter is having trouble coping

Recently, my wife was incarcerated. We have a 15 year old daughter, and she's been having a hard time coping with it. My wife feels a lot of guilt over what she did, I understand what happened, I've worked through it, and I know this is hard for her, so I've tried to give her some support. She's really trying to keep connected to our daughter. She calls often, sends letters, and basically begs us to visit. My daughter used to be really bubbly and talkative, but since her mom has been in prison, she's been more muted, toned down. It takes an hour just to ask enough questions to have her tell me about a class period at school. Her answers are short and lacking detail, where she used to chat with me for hours on end, no prodding. She got a lot more clingy with me- she was always a Mama's girl, but we were close- always hugging onto my arm or trying to hide behind me when in public. At home, she sits in her room until dinner, then we eat in front of the TV, and afterwards, she curls up in my lap until she falls asleep. She goes out with her friends less, I've had their parents ask how she's doing because she's so off when hanging out. She doesn't do sleepovers anymore, no more parties. She doesn't want to go to school have the time- it was her favorite thing a while ago.Everytime she gets a letter from her mom, she says she'll read it, but it goes unopened and put in a box in her closet (I found it while putting away her clothes, no snooping!!). If her mom calls and wants to talk to her, she's withdrawn, and barely responds, and tries to pretend like she's busy. When I say I want to go visit, she pretends to be sick. She'll be trotting around the house feeling fine, then I'll tell her I want her to go visit with me, and the next hour, she has a stomachache. Walking around the house complaining that she's bored, mom calls, and then she's going to the mall with friends.I just want to help my daughter. She says she doesn't want to go to therapy, everything is okay, nothing is wrong. None of her friends know. She won't tell them. I've asked her guidance counselor to talk to her, and she's very closed-off, and doesn't want to talk to them. Both my wife and my daughter's birthdays are coming up (Jan. 20 & Feb. 14), and I don't know how to approach them. Any advice is welcome. via /r/Parenting http://ift.tt/2ECFSO3
