My partner moved in with me over a year ago , he has son from his previous marriage, he learnt that I had been left a small nest egg from my husband that had died and is now always trying to borrow money from his dad. In the past his dad helped him out because he was single and could do so. His son has a well paid job as does his partner, but it doesn't stop him from constantly asking his dad for money because he believes it's his Dad's job to do this.
I'm worried because we want to get married but I feel his son will then see my inheritance as his inheritance.
