furious at over jealous husband!

Our air conditioner broke in the middle of a heat wave, the repair man said he can come tomorrow and repair it at 3pm. My husband will be at work but ill be home with the kids... my husband took it upon himself to cancel the appointment and re book it for almost a week later just so he can make sure he is home! The repair man is quite a older gentleman And because of my husbands ridiculous jealousy my 2 year old, my newborn and myself must suffer through sweltering heat for almost a week and sticky nights while he works all day in a nice air conditioned building. Things like this make me consider leaving him I've just had enough of this jealousy and clearly there's no trust in this relationship.
