Angry at my dad and I don’t want to talk to him anymore

Anyone else dealing with absent grandparents? My dad is living his best life, good for him. He left my mom when I was little, and he did the bare minimum for me. As in… tv dinners when we’d visit him every other weekend, watched tv all day. His parents (my grandparents) couldn’t have cared less about me, I made a point to visit them when I was older but they basically ignored me while I was there but praised my brother who visited half as often. So I stopped going. My dad will pop into my life once or twice a month and then disappear the rest of the time and I’m just tired of it. I’ve tried to talk to him about real things but he literally ignores me. I think he’s just completely emotionally immature, but he tells me about his new wife’s adult kids who he watches tv with at night, drives them to college, he bought them a house (!) and gave them cars and motorcycles. Luckily I’m financially very stable but it made me realize he gave me nothing besides the child support he begrudgingly gave my mom (even though my mom re-married when I was a baby).

There is a lot more to this but the summary is that I’m just feeling done. My oldest son is 3 and he knows ‘grandpa’ but when grandpa comes over he often ignores my kids and just goes on with his own stories of expensive stuff he’s buying, property he owns, and issues with his own mom.

I’m feeling anger build inside me and I’m reading a book about emotional neglect and it’s making me mad. I want to cut him off and just be done with him, but he didn’t actually abuse me or anything. I don’t know if this is even a grandparent that my kids need in their life.

My in laws are amazing, they still work but come help us every chance they can. We also have some close friends that are like family, so we’re not totally isolated.
