There are some magical interventions that might help you a bit in this situation. I might start with a Honey Jar spell to "sweeten" the situation.
Howver, if it important to remember that magic is not going to 'fix" the problem that you are having. All it can do is make those involved a bit more inclined to try to solve the issues. You are still going to have to do all the hard work of communication and openness or in the end the magic will fail you as well.
Along with the magic I would strongly suggest that the two of you seek out professional help with a marriage counselor to see whether there is enough left of your relationship to salvage. But remember, it takes two being willing to heal a relationship. If he isn't interested in fixing it there is no magic or anything else that can make this work in the long run.
