Male Virgos actions

I read everywhere that Virgos are typically upfront and straightforward and 'honest' - the honesty I'm not too sure about. Anywho, if you a male Virgo find interest in your gf's friend, or someone else - do you typically continue this current relationship, end it, let it fizzle out, or be up front about it. Like would you end a relationship with someone you've known a long time for this? How do you know there's an end coming?

There different types to the Virgo male. Some are upfront and hones for there convenience, some are only going to give you information on a need to know basis. I will give up to them, when they want someone, its well known. I feel it also depends on the maturity level of this guy.
