Long distance is like jumping into a serious relationship instantly with none of the benefits outside of your basic ones.
So unless you and the person really really vibe and have the same end goes when it comes to a relationship or looking for it to be long term or forever type thing don't do it imo...
It's good if you need space, and have other things going on because you don't have to worry about entertaining or being entertain by someone every couple day's out the week.
