2 Corinthians 6:14
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
In the end, these type of relationships offer major difficulties, which is why Paul wrote about this thousands of years ago. If your boyfriend “Hates” your Christianity, it may do well for you to consider the alternative of not getting in to deep and moving on before it gets to emotional and circumstances to involved.
There is a reason this issue is thousands of years old.
