<human>: Okay. So, I'm currently deployed and have been for about 8 months now. I was with my girlfriend for about 3-4 months before I left. Ever since the beginning there was another soldier (whom I have never met and she met through her friends) who has been trying to sabotage us from the beginning by telling her horror stories about dating military men and such. 

Normally I wouldn't let this kind of thing get to me, because hey, girls are going to get hit on. It's just the nature of things. But this guy is relentless. 

Well, time comes that I leave and every once in a while, he messages her and tries to meet up at all times of the day and night. One time, she asked about friends being there if they do and he says he's better with "one on one". At this point, I'm pretty sure you all can imagine what I'm thinking about his intentions. When I bring it up, she tells me he's "not MUCH of a threat". I emphasized much because that word really stood out to me. 

I ask her why she hasn't just shut him down yet and she never directly answers the question. I know being over here can cause guys to over analyze just about everything going on back home, but I can't help but feel like she's keeping him around as an option or something. This has been going on for a while now and he is not stopping. 

I want to handle this situation as delicately as possible. Should I try to contact him myself and just hurt his feelings? Am I overreacting? Should I insist she definitively tell him off? Should I STFU and trust her to handle her business?

Give me a shortened version of the text
<bot>: Guy keeps trying to meet up with my girl while I'm away. She won't shut him down. I want to handle the situation as delicately as possible.
