I would see if you can establish a "date night" or something together each week? That's what my husband and I did while we worked.

Do you work? Maybe get a couple of things of your own going (night out with the girls :-) or find another couple/family members that might entice him to hang out more. Does he have siblings or other relatives in the area? We go to my brother's or his brother's and have grown children/grandchildren (birthday party for grandson on Sunday :-)

Check how he treats his siblings/friends/parents and that's what his future is probably going to be like?
