Need help

Friend of mine met a guy from Houston Texas on eharmony. They've been talking for a few months. They talk on the phone 3 times a day if not more. She sends him emails and questionable pics he never sends her any pics. He has not asked for money and they've only discussed meeting sometime in the future. By the time it happens they will have been talking 6 months. The problem I have is she seems to be getting rid of her friends for this guy and it worries me that he's going to scam her out of something or even black mail her with the pics. I've done online searches and he has no profiles or facebook no images online although she claims to have seen a pic of him(ONE). Theirs not alot of info on him. I do know he lives in the states his cell phone is a Houston Texas number and his residence comes up okay. I just think he's using her for something. Can anyone shed a light on this or am I exagerrating?

Welcome to the forums bd. Without more specific information it's difficult to make a comment at this time. I hope it's genuine because it would be brilliant to see a good news story for once.
Your friend may be lucky but generally anytime you see military person + 'internet dating' = scam.
However it's too early to say at this stage.
May I strongly suggest your friend carefully read http://www.cid.army.mil/romance_scam.html because it contains valuable information and better describes than I could.
If friend is sending soldier emails, can you check the e-mail header of any emails that are returned? If the ip number does not match where his location is claimed, that would be cause for concern.

Well he's not in the military. I dont have access to the emails now, but I did originally do an IP search from one and it came up as a proxy and couldnt be traced. I've done email searches on his address and also checked his cell phone. It just strikes me as odd that theirs nothing on this guy at all. I do understand not everyone has online social network sites but you would think I could atleast find out what he does for a living? My friend is not forthcoming with information because she is stary eyed in love. Anytime anyone tries to ask her more about him she shuts down the conversation. It's just an uneasy feeling and as I said she's distanced herself from all her normal real life friends which I know people do sometimes when they are in love. What other information can I supply and maybe someone here on the forum could help out? Thank you.

Oops! My mistake.
One good aspect is the person has not asked for anything in a monetary sense after they've been in contact for the several months. Usually (but not always) scammers ask for money assistance after only several e-mails or couple of weeks.
re: "did originally do an IP search from one and it came up as a proxy and couldnt be traced." That is a ploy scammers use to hide their true location and no legitimate person would have no need to use. Distancing herself from friends is a bad idea.
I know I'm maybe asking too much, are you able to post one or two of the emails? Other members could then give their advice because perhaps someone else has received a similar message? What is the writing style like? Does the writer sound or write like someone out of Texas?

Thanks again for your help. No I cant get ahold of any of the emails. The ones I did originally get to see were pretty basic. They werent form type letters that most scammers use. In fact his letters to her are very vague. He will just write a line or two or maybe ask a question or answer her questions. Their really doesnt seem to be much of a connection thru emails. I think it's somewhat funny that they ONLY email and talk on phone but no texting whatsoever. I dont know if he's after money or what he is after that is the whole issue I am having. She blows off all her friends that have been in her life for a very long time. From all accounts she seems to be head over heels and he is more nonchalant about it all. I just fear that with all the racy pics she's sent him and she doesnt have any of him that something is amiss. I didnt know if their was other avenues I could use to search more info on the guy. Guess it's going to be a wait and see aproach.
