Help getting to neutral… where do I even start?

I’m headed for divorce (my husband’s choice not mine) and right now I hate him. I’m angry and judgemental. It’s been 2 1/2 months since he left and up until now I felt love and compassion in a way I never even thought I was capable of. That felt nice but it didn’t change the outcome of heading for divorce, in fact things with him got worse, so I’ve reached a point of frustration… and feeling mad about it feels better… I feel like I can accept it more now. But I know that’s not where I want to stay. I want to get to NEUTRAL. I don’t want to go back to feeling love towards him. Just neutral. But I don’t even feel neutral about getting to neutral!!! Where do I start?
