He is almost six and cannot entertain himself. He got home at 4:30 tonight. FDH needed to finish up some paperwork. I got him set up with a matchbox car racetrack and came down to do dinner/read. He was playing, but when I went up to take out my contacts around 5:30 he was lying in bed sobbing. When I asked why he said what he always says "I don't want to be alone." I explained to him that we were right downstairs and both doing some stuff and couldn't play that second. He said " but you never do anything with me." (Not true by the way. We went to a sporting event Friday night, a bowling bday party Saturday and MIL's for dinner Sunday and we took turns reading outloud during school nights this week.) When I asked him what he does at his mom's he said "watch his brother play video games or play video games". He will sit all day and watch t.v. or play on the iPad, but can't play alone. I don't get it. We do a lot of stuff together and eat dinner together every night. His mom has BPD and I wonder if he isn't developing so codependency issues. She left him from 18 months until 2 1/2, so I don't know if he developed some issues from that... He is over to his mom's every other week still. I am a total introvert so I am having a hard time understanding him.
