I’m worried he’ll resent me

Me and my boyfriend have been together for almost two years, I know it doesn’t seem like long but we’re very close, in love and know we want to spend the rest of our lives together.

At the start of our relationship he told me he wanted children and I know I never want children. I told him this from the start. He now says he has changed his mind and would rather spend his life with me, even if that means sacrificing having a child.

I’m just worried that in the future he’ll regret this decision and resent me. He says he has genuinely changed his mind but I’m scared it will change again.

I’m not really sure if I’m asking for advice here, but I really just needed to put this somewhere in hopes it will leave my mind for a while...
