I have copies of texts from my ex's phone which show lying and unreasonable behaviour. They also show evidence of my ex MIL trying to make the situation worse and telling him what to say to ensure he gets the children, the house and my money even though he told her it was mutual. He is unaware I have read these messages. Where do I stand in terms of showing them to a solicitor for evidence, am I better off not disclosing that I checked his phone?
