I'm 20F and my bf 21M are in relationship for 1yr. and im hella confusedd now.... I need a relationship advice!!

so i have been a relationship in my 18s with a boy (lets say A) who is way too toxic. I was with him coz he was my family frnd, and i was forced to be in relationship with him. he was too toxic, one day he made me feel like im his everything and the other day he was the reason i cry the whole night. he says we are not in relationship but wants me to act like one and get jealous. it was clear that he is not at all serious with me he commented, body shamed and wt not. i gained all the courage and said no to him and blocked him from every platform and from my life. meanwhile, all this is happening, there was another guy (lets say B), who liked me. he is pure opposite to A. he is too good and greenest flag. we were very good frnds, and i knew he liked me back then. since i was (not) in a relationship with A, i couldnt say anything to him. i felt guilty, heavy and many emotions, that i had to take a break from B and not talk to him for like 4 months. After i bolcked A and removed him from my life, I still was confused to be frnds with B coz, i knew i hurt him. Anyhow, we came back, became very good grnds. He knows abt A. I was healing from my relation and from A, and B always helped me in healing. He came to knew that i had feelings for him and we had many deep convos. in one of the convos he said that he knew i like him, then why not confess. he said while healing, if there is someone emotionally available, u will heal faster. upon hearing that, i confessed to him. We are in a relationship now. But i still feel guilt. i feel like im not fully healed and over dependent on him. alongside, he always tells me and say lectures me, when i need someone to LISTEN and not SPEAK. When ever i share my feelings that are heavy, he gives solutions while i dont want solutions, coz i already know them. I just want someone to listen and understand. i said abt this, and now he is changing and i feel so blessed for having him. but sometimes he becomes too irratational. he asks abt my past even when i say i dont want to, ask how i feel abt him and all, he lacks confidence on himself. i say that i love him and all and yet he still isunder confident. he doenst understands me (he tries too) and he is such apure soul, i dont wanna hurt him. To be honest, he is a lil emotionally immature. i thought he will gradually learn but i dont feel that coming. while talking he sometimes mentions " U will handle and manage me, im so lucky" this sentence gives shivers to me. i dont want to handle anyone. i want someone who is independent and can handle himself. i feel he is being dependent on me. i know i should communicate abt this to him, but im afriad that he will overthink abt this and get hurt and i dont wanna hurt him again... even his family is kind of orthodox. they wont understand all this.... i'm hella confused. Honestly, he is soo good, he loves me a lot, cares me a lot, but at times i feel its over love and over care. irony is we all need care and love and when we get excess of those, we fell overwhelmed. even more irony is that A didnt care or love me a bit and B loves and cares me overly. How do I communicate my needs without hurting him?
