I do not have good news for you.
There is no claim for them cheating.
If the marriage is over you can make a claim for property and spousal maintenance. But you cannot sue for them cheating on you there is no compensation for that.
When you do apply for maintenance and a property split there is no compensation because it is no fault system.
The reason for the split does not come into consideration.
I am sorry I cannot give you anything more positive.
