We are selling our house and looking for somewhere bigger. DP will possibly be getting a sizeable inheritance which he hopes to put towards the new house. I don't want him to use it because it would mean we no longer own half each. Our relationship has sometimes been shaky since dd's birth and he has today said he will be putting the inheritance in if he so chooses because he is 'the one who makes rational decisions' in our relationship.He also says he wants some sort of clause stating that he is the majority shareholder e.g. 60/40 in the event that we split up in order for me not to steal hos money by demanding half the house.
I really don't want anything to do with this inheritance whether we stay together or not. Is he being reasonable?
