There are several questions for women who doubt the depth of their partners' feelings:

Do you think that his love is not real because he pays little attention? If you found out that it is true, how would you feel? How can you get this feeling in another way? Can you feed yourself with love? If so, how? What would you like to ask a partner about? What to find out? Is there any anxiety due to the fact that the relationship is on the verge of breaking up? If so, is this belief reasonable or do you just feel that way? On the one hand, we are familiar with that feeling when we are not loved. And yes, this feeling can be justified. It’s as if we tend to transfer old experience (our own or someone else's) to the current relationship. As for true love, try to understand: what is it? How do you feel it, what do you do and what do you get in return? And most importantly, gradually give this love to yourself. Then you definitely won't make a mistake.
