Does it matter if my boyfriend is flirting on Facebook if he never sees her in real life?

I had talked to my friend and she said it was emotional cheating but reading through their messages he made it pretty clear he didn't want to see her in real life .. So nothing really detrimental can happen . I'm SO angry that he's chatting up another female but I don't think he would ever have sex with her. This is the first time I caught him flirting with another girl also

So my boyfriend is flirting heavily with this girl that lives in our city.. How do I know this ? I snooped in his Facebook and read several conversations. It's crazy that he writes her so much. Me and my boyfriend have been dating for 2 years and we see each other almost everyday .. He only facebook messages her.. So I guess I have the upper hand
I have met her plenty of times in real life cause she used to go to school with me but my boyfriend said he's only seen her once and that was from afar. I still haven't told my boyfriend I was snooping on his page .. I don't think I ever will.
So the Facebook messages go like this
The girl : come meet me at the movies
My boyfriend : I can't case.. It wouldn't be right for me to be meeting other girls at the movies .. I know I wouldn't want my girlfriend meeting other guys at the movies .. But one day we will see each other "
The girl : I used just wanted movie company but have it your way

Fast forward to like 5 days and this is how the conversation goes
Girl : you're too lame. It's a problem
My boyfriend : you need my lameness
Girl : I don't know how two extremely lame people could possibly be friends
My boyfriend : you're a living witness
Girl : I'm retiring from my lame ways
My boyfriend : you can't I won't let you . Knock knock
Girl : who the hell is there
My boyfriend : you was lame enough to come to the door though
Girl : you make me cry everyday .. I hate you
My boyfriend : you not crying first of all. Second of all, I make you a happy go lucky person

Dude, dump him. Seriously

C'mon - you know the answer to this.
Dump him. It IS cheating, and that horse has already left the barn.
You deserve better - lots better.
Go find it - it certainly isn't him.

A lot of the importance of this situation should be weighted with regards to both everyone's ages/stages, and the amount of secrecy involved. If your boyfriend knows you can read his Facebook account (which he probably does) then he's not actively hiding this. If you all are young, unmarried/uncommitted people, then that also makes a huge difference. Do you live with one another as a couple? That would make this more of a deep concern and require confrontation, if only in a mild way at first. If not, then it's the vagaries of a non-transparent relationship that is often the fate of those who are dating and unsettled. The other girl is not the problem. The lack of transparency between you and your boyfriend, however, is. Speak with him, nonjudgmentally and without angst, simply ask him if he's interested in other girls/women and if he flirts with them. Under no circumstances should you start out with a confrontational manner, yelling or saying vehemently, "I saw it in your facebook page!" Just be calm and let him speak. From what he says, decide what you want to be or to happen and convey it to him, calmy and gently. If it's not clear enough for you, ask for clarification. If it's unacceptable to you, tell him so, and let him know what you thought you two had, and what you want. If he's not at the stage you need him to be, tell him good bye as a boyfriend, then decide if you want to keep him in your orbit as a friend. This situations must be clarified. Think of a mirror. Does your relationship with him look "dim" or "muddied?" Clean it up, first. At that point you can decide what shall be done.

I don't know, DOES it matter? Only YOU can answer this for yourself. It matters to me, I would NOT be ok with this at all. But if you are ok with it, then you are ok with it. It doesn't really matter what anyone else thinks. It does make you sound pretty desperate though, to be making up excuses and reasons why it's ok. Pretty pathetic that you don't think you can do any better than a lying cheat.
