breakup :(

hi everyone, my boyfriend & i were together for nearly 4 years until i broke up with him yesterday.

i love him with all of my heart. i care so deeply for him. i hate that i broke his heart. but, something within me let me know that i wasnt happy & was not fulfilled.

im 18, im very young, & im going into a very tough career where i feel like i need these next few years alone.

i just want to text him & ask him if hes okay. im not going to bc that would be unhealthy for both of us but its so hard.

any advice? i feel guilty for even being this devastated since im the one who broke it off.
