Is it worse when we love a man more than he does or vice-versa?

Do you think it's worse and more hurtful when we love a man more than he does and commit sooner or if he loves the woman more than she ever did. There are two scenarios:

It's a long-term relationship (3+ years) and she's already thinking about bearing his kids and he's still on the "romance and sex. . let's go to the movies and have fun, dating" stage and doesn't feel strongly about her, not enough to form a family with her. She loves more him and gave too much dedication.

They've been together for 2-3 years and he really loves and trusts her. He's the one bringing up conversation about kids more than she does. Or somehow there is a miscommunication, he really thinks she's the one, willing to give up his freedom, even proposes but she declined it. He's hurt and upset after realizing he loved her more than she did.

Which is worse, more hurtful?
