My DP has a constant habit of falling asleep on the sofa half of the night while I go to bed early. There's now been numerous occasions I've gotten up in the morning or middle of the night and he is fast asleep with a fan heater blasting. This morning is the straw that broke the camels back. I leave for work early and just had an urge to check nothing was left on as he had only came to bed half an hour before I got up. I went into the lounge and there was a storage heater left one and had clearly been on all night as the room was sweltering hot. He'd also left a bottle of red wine on it to heat up which he hadn't even opened.
I am feeling really pissed and was ready to march upstairs and wake him but stopped myself. 1) I feel it is so dangerous to leave an electrical storage heater unattended (especially with a glass bottle on it) 2) he is wasting money and it's half my money that will be paying for this ridiculous waste.
I know I am probably overreacting so I am here asking how to bring this up properly and am I blowing it out of proportion? As I say, this is not the first time he's done something similar but going to bed and leaving it on and the wine bottle is a bigger issue as I think it would have been on all day had I not went to check. Feel like I'm living with a teenager.
