Is this normal ?

My spouse went ahead and sold his second truck for a car for his 13 year old and didn’t feel it was important to at least let me know . I feel as if every time there is extra money it goes to things for just him and his son. We have been married for a year and we haven’t even celebrated our honeymoon.so I do feel some way about it because I been helping him save and our savings are to buy a house . Every time he saves a good amount he blows it on something for him or his son . The last saving we had he bought a truck . So o feel like it’s unfair.
