Not taking anyone in my life after divorce with my ex, for nearly 12 years make me stupid in ex's eyes?

He is my ex husband. we have twins at the age of 11. He had many girlfriends all these times. One who were from Brazil and online chatting with my ex only and living Brazil ( My ex and I live in Europe.) even wrote me by messenger and told " he doesn't like you anymore" .. I left him alone after her. But in 3 months he came and appologized me, he even gave her nude pictures to me.
After this event, i never had sx with him. He wanted but i didn't let him.
But i dont take anyone in my life. Because basicly i just dont want. I am very busy with my twins and taking care of them.
My ex sometimes says, date someone. I asked why he said this. He doesn't reply me.. When i been silent, she start to send me love songs.
He didn't get anyone in his life formerly and introduced to his family.
