Wow! That's a pretty big decision. You do realize you're going to break her heart don't you? God is all about love and I don't see any reason why he would want you to leave her. I'm not saying to sin and choose her over God. I'm just saying that maybe you should try to find a way to serve God while loving her. Think what that could do to her spiritually. She could deny God because she may think that God is the reason she is heartbroken. I'm not trying to be disrespectful of your decision. I'm just trying to see if you made this decision by considering her feelings and your love for her. I hope things work out for you.
