Addiction and relationship problem.

I have been texting my childhood crush more than 1 year through way2sms app. He blocks all my calls. He doesnt block me on way2sms. He blocked me on fb and whatsapp too. He is my twinflame runner in short. We havent met, but i am very much interested in him,he too had a crush on me, little. But we didnt meet, it was just an unknown attraction. He is an computer science engineer from great university. So he developed a program to block and unblock me everyday from my number after certain message limit. I contacted his brother, he said my life would change. I have quitted my job, i dont know who this person is much, only through social media,he was a childhood friend..i wasnt able to delete him from my mind.. I am trying to come out of this texting habit...But i need to heal quickly..lot of energy wasted from my mind..
