I feel like my dad and grandpa- especially my dad- gave me unrealistic expectations for a man.

I was an only child for 10 years, the first grandchild and first niece for my mom’s siblings.
I was extremely spoiled by my parents and grandfather.
Each time I wanted something my grandpa would buy it for me without question. He has sadly passed away but I miss him so much.
I now have three younger sisters but still to this day I am my dad’s favorite and whatever I want he will give to me. Each time I want money he gives it to me. He doesn’t let me pay rent or do chores. He doesn’t even know what to buy me at this point for my birthday or Christmases since I have anything I could ask for. Keep in mind I’m 24.
I am self aware but it’s so difficult letting go of certain expectations you were brought up with.
It is difficult because when I’m dating a guy, even if he’s sweet and caring I subconsciously expect him to buy me lavish gifts, take me places and give me attention constantly. As soon as they stop doing any of that- whether they’re busy, or don’t spend money on me I usually break up with them. I think it’s because material things were really ingrained as a form of love to me for as long as I can remember.
Im trying to let go of that but it’s so hard.
Just venting.
