that boy

so this is also about the boy that i mentioned in my previous blog. i basically cut ties with him. i feel so selfish for doing so but i'm really scared. he used to send me a lot of sexual and suggestive messages before and now he won't let go of me. he keeps texting and calling me. he even created a new account to just contact me and to say that he missed me. i don't know what is right at this point. i always tried to be there for him but it only made it worse for both of us. he used to say things like "i want to die with you" or he'd just imply killing/stabbing me. he invited me over his house and said that he feels lonely. i don't know why i can't let go of the past but i'm scared i still want to be there for him. i know he feels sad and depressed
