How do you turn off love?

It has been 5 months for me since D&D and I've been NC the entire time. I feel like I understand the disorder and frankly I'm sick of trying to understand him and what he did and I want to focus on me. The thing that I am finding hard is I truly loved this man and his daughter. This was my husband and I was a step mom. I get that he didn't love me but I put 100% of myself in to making our marriage work. I don't love how he treated me. I don't love the stress and pain that he caused. I don't love the false him that was sweet to me in the start. I fell in love with the man who showed me that he wasn't perfect. The one who had the inner struggle pulling him from doing the right thing. In other words, I didn't fall in love with the perfect person he tried to create, I loved him despite his flaws.
In no way do I want him back. I'm just finding it hard to stop loving him. It doesn't just go away over night. My entire life was my husband and kids. I'm not sue if this makes any sense. What he did wasn't love but my love was real. How do I make it go away so I can move on and continue to work on myself.
