My girlfriend's co-worker is starting to cross the line and not sure what to do about it?

My girlfriend started working at this store a few weeks ago, employment for the time being until she can find a job that makes use of her education. But one of her co-workers is seriously getting on my/her/our nerves and he's kinda crossing the line as far as co-worker/lady-in-relationship communication goes; and my girlfriend agrees but she kinda tolerates it Because they work together and nothing drastic has happened yet. I definitely do NOT feel threatened by him, everything I'm writing here has been communicated with my girlfriend and she understands where I'm coming from. He's been nice enough to help my girlfriend with rides from time to time, which is totally decent of him, but his intentions aren't genuine because he's made it clear that he has a crush on my girlfriend. We think his attitude is seriously whack, he's kinda arrogant, and it's kinda screwed up on a "guy-code" level in my book and he has met me several times and knows who I am. So what kind of crap is he pullin? He texts her almost constantly, and the days that she doesn't text him he tries to put guilt trips and says stupid crap like "so you giving me the silent treatment today?" "you miss me?" "does yer boyfriend hate me yet?" wtf?!?!?!. He also caused some very unnecessary drama for her at their work when she was sick, kinda hard to explain but he basically is trying to play superior on a new co-worker when he has no rank, and only been working a couple weeks longer than her. She snapped at him for that, and told their boss, but he's trying to create a situation that makes one or the other seek apology or sympathy for their "friendship" which is really just co-worker situation and they really don't even know each other.

There's just some stuff you just don't do, and if you do do that then you should expect all/any type of negative response you get. I've never been in a fight before, I'm not some territorial meat-head, I trust my girlfriend, she tells him to back off but he doesn't. I feel that I should make him aware that he's behaving inappropriately, but I'm NOT gonna do that at their place of employment. If I'm gonna say something, I'm a straight-shooter and I'll tell it to your face. He's starting to deserve getting his ass-kicked, he's seriously irritating us, and I wouldn't be surprised if I just made him aware calmly firmly and maturely that it bothers me he'll probably get scared, and I'm not looking to do anything that will make things bad for either of them at their job. I'm just wondering and am a bit torn as to HOW firmly I address it. I'm not physically threatened by him either, and we jokingly say it'd be fine to kick his ass when she quits Because he deserves it, but I feel it should be addressed before that otherwise it's just gonna get worse. It's kinda disrespectful towards my girlfriend and me, don't ya think? Any advice? he deserves an ass-kickin but obviously there's some reason to hold off on that for a bit. I'd appreciate all and any feedback. thank you

My girlfriend and I hung out with this turd last weekend, he's still a douche, I feel better and more annoyed at the same time, but now I'm keeping it more in my gf's court to handle it. Sooner or later I'm gonna confront him. still seeking advice and perspective

seeking more perspective rather than advice I should say. Everyone seems to agree with me,and my logic for it but I haven't heard any success stories or actual "I was in a similar situation, so I did this..." yet. So I'm kinda still hoping to hear that.
