Okay so I want to know how you draw the line as to who is off limits. Best friends GFs, clearly no way. But what about girls who the downside is actually a huge risk to other parts of your life (e.g. job), where you feel like 90% sure you got it but know that 10% would really make you miserable. Total no? I know the whole oneitis concept and being indifferent to outcomes but I still find myself in these scenarios where I just move on to someone else and then sorta realize that maybe I shoulda gone for it.
