DS aged 13 goes to a sports club on Friday night. It's also the night that exH is supposed to pick him up every other week for his weekend. ExH hasn't picked him up on a Friday night for a long time and I mean probably only once in the last 18 months meaning that he either picks him up Sat AM (often 2 hours or so late) or doesn't bother at all, he currently hasn't seen him (or phoned him) for 6 weeks.
DP and I have decided that if ExH does pick DS up this weekend that we will stay away in a hotel for the night and although I won't believe it til it happens, it will be lovely.
Having spoken with ExH he has offered to pick DS up from school tomorrow, which would be great, really lovely for DS who has only once had his Dad pick him up from school in the last 9 years , but a. he might change his mind have last minute work commitments and b. he also won't take DS to his sports club. When I asked if he would take him I got told that he would rather pick DS up on Saturday morning. 
DS didn't go to sports club last Friday as I went to a wedding and couldn't get him a lift and now I feel guilty if he doesn't go this week too. He could go to an alternative club on Monday but I have agreed for a family friend to come round for dinner now.
DS won't really mind if he misses the club but I don't like giving the message that it's not really important.
