Mishka, it is sad. We all have periods when we doubt whether it is MLC or whether they just got tired of the marriage. Some spew, and some don't. It isn't obligatory.
If you were happy, and it was sudden, and he had a difficult childhood, and a tendency to suppress difficult emotions that he didn't want to deal with, chances are it is MLC, but I am not expert, and I don't know your h. Like I said, this is our chance to make the inward journey. Personally I don't torture myself by listening to music that brings back memories. Someday I will be able to but right now I know I can't. Now is my chance to discover new music and create my new memories. Try and make every negative into a positive. A bit pollyannaish, but not a bad discipline.
Our society is not big on emotional self discipline and self knowledge - good on not smoking, drinking eating too much etc but we need to develop this side of us, and doing it emotionally alone [even as we are surrounded by family] is possible. Eventually I believe all our relationships are enhanced by our spiritual growth.
