When people have a hard time loving themselves, they have a hard time loving others.
I do know that my husband loves me. Does he treat me like he does? Often, no.
In my experience with him, and I can only speak to my experience with him and no other's experiences, he loves me the best he knows how to.
It is said love is actions not words. Someone on here recently mentioned that. I agree that healthy love can be seen in actions - but if it's healthy the word and actions match up pretty well.
If the individual has a hard time loving themself, those things may not match up too well.
On the other hand, people who hate each other are nice to one another's faces.
So I don't think my husband doesn't love me. I think he struggles to love himself and does not know how to love others in a healthy way. He doesn't feel worthy.
Breaks my heart.
