Call Womens Aid 0808 2000 247 and have a look at their website . If he has been undermining you in this chilling way and you're finding it hard to think straight, you are going to need some informed support to make your way out of the situation. Womens Aid lines are busy now and the best time to call is between 7pm-7am but if you can't manage that then leave a message for them to call you at a time that is convenient for you. They won't leave a message unless you specifically state it is ok and the coast is clear - they refuse to identify who they are because they won't put you in jeopardy.
we tend to think that domestic abuse is physical eg hitting but all victims of domestic abuse state that it is the mind games that are far worse than the hitting. It is not you who is mad, it's him. It's a chilling story but, sadly, not the first. As a pp said, what he is doing is called gaslighting - here is something I found on the web:
Gaslighting is a form of psychological abuse in which false information is presented with the intent of making a victim doubt his or her own memory and perception. It may simply be the denial by an abuser that previous abusive incidents ever occurred, or it could be the staging of bizarre events by the abuser with the intention of disorienting the victim. The term ?gaslighting? comes from the play Gas Light and its film adaptations. In those works a character uses a variety of tricks, including turning the gas lamps lower than normal, to convince his spouse that she is crazy.
Interesting that he turns up the gas to ruin the food (ok, it may be electricity but you get my point).
when you get Womens Aid on side they will support you to make your way through the maze he has created around you. Well done for spotting it (I'm not being patronising, it is often hard to get your head straight enough to see it). They offer comprehensive support - listening and supporting but also practical support eg benefits, lawyers; also support to practically escape from an abusive relationship.
somewhere down the line it might be an idea to do the Freedom Programme which is an excellent course I highly recommend to help you get your head straight about what has been going on. Click the 'search' button to find a group near you - it's 'good' to meet with other women who are experiencing similar things.
I'm sorry you've had a rough time and I wish you well. Many of us have got out of relationships like this, you can too.
