Internet access as a reward

[Forestdweller11]

Aibu? Doing a household task together DD is being a bit slow. DP tells DD that she can have more internet access if she speeds up. I say it's pointless as she's allowed access if she wants it from 6.30am until 11pm anyway so where are these extra hours to come from? DD ends up with 4 hrs worth of extra time. I again say where is this extra time coming from? I also pointed out (for the second time) that I control internet access anyway not DP so he shouldn't have promised something he couldn't deliver on. (Anything like this - the wife work basically- DP shows no interest in, ever)

FF to 11pm tonight internet goes off for DD I'm then told by DP to give DD extra hours tonight. I say no, 11 is quite late enough. DD doesn't want the extra hours tonight. DP tells me to give the extra hours now and that I'm undermining him. I say again no. Apparently I am a self centred twat who is being deliberately controlling over something that doesn't matter. I suggest that if DP is so bothered about this he gives DD his laptop for the night (as his isn't blocked). Cue much comments about me being a confirmed control freak. DP then goes to bed. DD is also asleep by now...

I'm sat fuming.

Was ibu for not adding on the extra hours when (a) DD didn't want the hours tonight and (b) saying at the time that more hours was not possible?

What a lot of bother, I couldn’t care less how long a task takes as long as it gets done, can’t be arsed with bribing. Maybe your DP knew the extra time was pointless but was showing your DD that he does have some say over her

Why do you control the internet access

If you control the access, you could have just allowed more, right? Why not give her an extra hour or two Friday and Saturday night? How old is she?

This whole situation is bizarre.
Firstly, that it matters how long DD takes to do a household task (unless someone is waiting for her)
Secondly that 6.30am-11pm is even considered restricting internet hours.
Thirdly, that if she's old enough to have internet from 6.30-11 and she wants to have it, she will get around your "rules" so it's a pointless incentive.
