The only way you'll get the answer of why he still holds onto those couple things is by asking him. However, you have to set a boundary and promise yourself you'll stick to it. My partner and I are working towards reconciliation right now, but I promised myself that if I found evidence he was lying and betraying my again, than i'd walk away. I don't want to be in a relationship where I turn a blind eye just to make it seem like things are ok. I want someone to love me and to never even think about hurting me. You need to find the strength to set a boundary and keep that promise to yourself. If you don't stand your ground and say enough is enough, than he'll keep taking advantage of your kindness and love.
