To have lost the plot with DH

[Ipushedmygrannyaffabus]

Tonight DH lied to my face. I took a sip of his drink - which I thought was a soft drink) and realised it had alcohol in it. Asked him what was in it & he denied denied denied it was alcoholic for about 10 minutes. I went mad (about the lying not the drinking) and was yelling in his face.
Months ago, when our baby was newborn, he treated me terribly when he was drunk & was drinking too much. It was his decision to stop drinking during the week & stay away from spirits but was also the only reason I took him back.
He previously had a drug problem & used to lie to my face about that too. I refuse to be treated like an idiot again. I've asked him to leave and he is now packing (whilst shouting abuse at me). Have I over reacted? He didn't even try to apologise.

Thank you all. Having my baby has given me a strength and a clarity I didn't have before. I will read up about gas lighting. He is saying he lied because "he knew I would go mad about his drinking" but that's bullshit and I told him so. He's currently staying with a family member to give us both space and is about to go away with work for a few months, which is even better. Any feelings I had for him have gone over the last few months and he knows this. My baby is literally all I care about now.
