I set the rule for myself because I didn't want any distractions on my mission. I'm concerned though because even though we're not officiant dating, she's one of the first things I think about in the morning, usually the last thing I think about at night, and in between I'm usually trying to come up with excuses to talk to her. We've openly said that once we're back from our missions, we'll give things a real try, and I'm worried that might be a bad idea to say that Can it be just as bad to want to be in a relationship as to actually be in it. Matthew 5 says to look upon a woman and lust after her is the same as committing adultery in your heart, and since the issue with relationships (in regards to distracting on a mission) is the heart, could this relationship I have with this girl be a distraction? Just to be clear, there is no lusting or anything like that going on, I'm not that kind of guy, she's not that kind of girl, but I'm still slightly torn between risking not giving 100% to the Lord, and risking messing things up with my best friend
