Not enough affection (ad/hd husband and non-ad/hd spouse)

Am I the only one that is having this issue my wife came to me today and said that she wanted a divorce. That I spend all my time on the computer and that she is just tired and fed up. She says that she has begged with me to come to bed or watch a movie with her. I am a college student going on to get my Ph. D. after my bachelors. We have 2 kids the youngest 2 and the other 10. I am still in love this woman she is the love of my life what do I do. Is it me or the Ad/hd? I am on aderallxr 20mg. We just recently found out that my anger came from this accursed disease.  The anger is gone now I can hardly eat and I am up all night. Yet the having to be asked multiple times still has not gone away. She says the only time i kiss her is to say hello and goodbye. I rarely give her any hugs. And we have not had sex in months I thought everything was okay up until today when she told me she wants a divorce this is my first time posting on the forum so I am hoping that I can get enough responses so my wife will at least take a look at it. Her exact words is not everything can be caused by your ad/hd. I love my wife with all my heart and soul I just don't know what to do to fix it.
