Help! my husband spends mre time on the the computer than with me:(?

have been married for only 7 months. before we met hubby was kinda a computer nerd? , then started dating and he didn't spend much time on the computer at all because we were always together. now married and 6 months later is back on the computer as soon as he gets home from work. till we go to bed. maybe a few breaks in between but the majority of the time hes on the computer. I miss his company, i have told him how i feel. even wrote him a letter. i feel like know that we are married he feels that he doesn't have to try any more. he says im being silly when i tell him how i feel. he doesn't give me very much affection any more. what do i do?. i want the man i married back! , the man that couldn't give me enough attention and love, who couldnt get enouph of me.i dont have a problem with him going on the computer. but when he spends more time on there than he does with me...thats when i have a problem. help?
