Do I have a right to be angry that my now ex daughter in law left my son because she’s lesbian

I’m angry because they have a son together, was married for 3 years, was together for 10 years (met in HS and they’re 25 now), he bought her her first car when she was 16, I opened up my home for her when she was in an argument with her parents back in high school several times, they had an apartment together and now my son is crushed. Good for her for being her true self and happy, but it pains me to have my son claim that time was wasted and he felt used. They talked about a second baby and a whole life and he truly believed that would happen. After him not only providing for her and getting them an apartment right out of high school and before marriage and a baby and helping her pay for college and have a safe vehicle to get around, he’s living back home with me and has lost his trust for others
