Name Changed for this. Me and dp both finish work a similar time on Mondays . He works a 20 min drive from home and and I use the bus which takes 50 mins opposite directions to each other. So seeing as it was dd school play I asked him if he could pick me up and drive me home so I had a bit extra time to get changed. It would work out he would have an extra 20 min journey but I would be home half hour sooner. Sorry if this is confusing. Anyway he said no as the extra driving would make him too tired to go to the play and he doesn't want to miss it. I say ok I understand I will go straight from work to the play and meet him outside the school. I arrive at school he's not there! I text him and he says he has just got out of work and is running and to tell dd he's really sorry! Not the first time he's been out late so think nothing of it and actually feel bad for him that he's missed play. Anyway.... Tuesday morning I get a txt from a mutual friend who works with dp saying ' I'm so grateful your 'dp' gave me a lift home yesterday the weather was awful wasn't it' I was like 
so he lied and was actually 5 mins from the school anyway! Sorry if this is all confusing but I'm angry
