So sorry to hear what you are going through. Being left out by someone you love can be really painful.
Can you answer few things:
-> What was the main reason of your fights?
-> How the family got involved?
-> Is your husband is inclined in getting a divorce or family members are forcing him to do it?
Maybe the solution of your problem lies in the answer of the above problems.
When things between a couple hit a breaking point, family involvement can help fix things. However, it's important to know when to put a lid on it as not stopping it in time can also make things worse.
I do not know much to go with. But based on what you have told me, it may be a good idea to reach out to your husband and keep the family, both sides, out of it as much as possible.
Hope that helps.
