Hello. It is evident that you care about and love your boyfriend. You are concerned about his feelings, and he occupies a significant portion of your mental space. This is reminiscent of Faye Wong's song "You are happy, so I am happy." His sadness has also become your sadness. Your genuine feelings are heartfelt.
Furthermore, you perceive a multitude of conflicts and insecurities within yourself, which, when coupled with your boyfriend's current state of being, makes it challenging for him to provide the care and support you require. Even when you need him to respond, he may not be able to do so. It seems that you are also unable to express your feelings and demand more from him, let alone blame him for your situation.
I believe that at this juncture, you would benefit from a great deal of care and attention to yourself. Many individuals in a relationship assume that if they are unhappy, it is impossible for their partner to be happy, because that kind of love is not sincere enough and is too self-centered.
It is important to note that there is no contradiction between paying more attention to oneself and feeling "not loved enough." This concept can be illustrated by the example of a flight attendant instructing passengers to put on their own oxygen mask first before assisting others in an emergency.
Individuals with depression often perceive the word "fighting" as a threat. They may experience guilt due to their inability to fully internalize the encouragement provided by others. Given the difficulty they face in regulating their emotions, they may also engage in self-blame, questioning their ability to experience happiness. It is unclear whether your boyfriend has received formal treatment or psychological counseling. However, these avenues represent a crucial step in providing him with the necessary support.
Once he has processed his feelings and needs, you may wish to invite him to discuss the type of love he desires.
It would also be beneficial to ascertain your own expectations regarding the nature of the relationship.

I understand how tough this must be for you. It's important to take care of yourself too, and maybe expressing your feelings to him could help both of you connect during this hard time.
Sometimes just being there can mean a lot. Maybe let him know that you're willing to listen whenever he feels ready to talk. Even if it's through messages, your support might give him strength.
It sounds like you're both going through a challenging period. Perhaps suggesting professional help could offer him new coping strategies. You can't carry this burden alone; it's okay to seek assistance.
Your intentions are so pure, wanting only his happiness. Have you thought about writing a heartfelt letter? Sometimes words on paper can convey emotions that get lost in digital communication.
Feeling helpless is natural when someone you care about is suffering. Try to establish a routine checkin without pressuring him. Gentle reassurance can sometimes be comforting without overwhelming him.
