Do you think it’s quite possible to be addicted to someone?

We talk about addictions surrounding alcohol, cigarettes and other extra curricular’s but

I could go months without a drop of alcohol but I can’t seem to go twenty four hours without a message from him

I don’t know the best course to take here, is there such thing as cold turkey from someone so addicting?

I feel the effects of the addiction to him coming on strong, I can feel in my heart that he doesn’t make me happy anymore but for some reason, I can’t let him go and it frustrates me to no end.
