Because you see the good in him, because you want to believe the promises and that the good times are the real him, because the chemical reactions their behaviour has caused in us has tricked our brain into survival mode, because they keep us in a fog and convince us we’re the problem or part of it, that we’re overreacting or imagining it. We aren’t dealing with ‘normal’ here.
Someone wrote on here once that people leave relationships all the time in the world, one party might not agree but the parties separate and move on, that hit home, we’re not ‘allowed’ to leave them, they won’t make it easy and again we want to stay safe. Don’t beat yourself up for trying again and again, he’s the problem not you xx
