Feeling insecure about my education level in dating

just a little background on me it’s been two years since my last relationship he was a business owner and only had a high school diploma just like me we both never finished College but he was successful and I also had my own business while working a 9-5 so I felt equal to him intellectually wise…I’ve recently decided to start dating again my friends keep matching me with high educated accomplished men, I’m talking Master Degrees/PHD’s and I’m feeling insecure because i only have a high school level education I just feel like I wouldn’t measure up to the men they’re selecting. Are there any girlfriends out there who have successful relationships with men who are high earning and educated? Do you ever feel small? How can I overcome this?
