Background info so as not to drip feed:
- DH has access to both landlines and his mobile for majority of the day
- Me having the car most days over half term was pre-arranged between us at the weekend
DH and I share a car. I dropped him off at work (approx 6 miles from home but can take up to 30 mins in traffic) this morning, went off and did what was planned with the DCs (2yo & 3yo) and he told me that he would be done and ready for a lift home by 4pm. Not a problem.
Drive to DHs work on my way home, arrive by 3:50pm, pull up and wait. 4pm comes and goes, no DH. Wasn’t too bothered at that point, running a few minutes late isn’t a big deal.
4:30pm comes and goes. No DH. No text, no phone call to acknowledge that I’m there or that he is running late. Not really worth driving home, which can take 20-30 mins in traffic, only to come out again soon to get him when he’s actually ready 
4:45pm comes and goes. Kids are obviously getting bored and antsy in the car, still no text or call from DH to let me know what’s going on. So I send a text saying that if he’s not ready for a lift in the next 5 mins then I’m going to go home and sort the kids dinner and he will have to get a lift home with someone else.
Out he strolls at 4:55pm, with a face on because I sent an antsy text
No apology that the DCs have been stuck in the car for best part of an hour waiting for him or any acknowledgement that it may have been courteous to ping a quick text that he’s running late 
I don’t know if I’m being pathetic in my rage, but I’m seething. It’s as if he honks I plan my entire day around being his taxi service!
Would you be mad if your DH did this?! Or am I just being a twat?
