I barely see them at night and weekends.. I just presumed it was a teenage thing and accepted it. sad
It really doesn't have to be and you have the power to turn it around.
Start of doing small things eg pizza hut, pub restaurant what ever.
Here is a list of some of the things our teenage boys have done with us ( they are 21 and 18 now) Although it's only a suggestion of things to do and no doubt you will have your own interests that will give you some common ground with your kids.
Go hiking as a family once they became teenagers they would bring a friend. More recently girlfriends come to!
Mountain biking- They are more skilled than us now but never mind!
Occasional cinema.Not so much as a 1:1 or as a family but it still happens, maybe once a month.
In the last 4 years DS1 has been draggging me to the gym!
We go to gigs together sometime. The last one that all 4 of us went to together was about 8 months ago but DS1 and DP went to see The Courtenners not long ago and I went with DS2 to a gig at the Academy in Manchester 2 weeks ago.
Go to Ice hockey matches together, home and away games as well as going abroad to watch the European games.
We don't live in each others pockets and DP and I have our own social life without having pesky kids with us all the time! They have girlfriends and lots of friends but we do seem to enjoy each others company as a family.
