My friend is living with her internet boyfriend after 3 weeks! - 30% Normal

One of my best friends recently started talking to a guy online. He lived in wolverhampton and she lives in hastings. Once they had been talking for about 2 weeks they told each other they loved each other, then he came to visit her. They hit it off really well and now he is moving in with her in her parents house and her uni rooms during term time. I am very happy for her that shes found someone that makes her this happy but I am worried because it is all so quick. They have been going out for less than a month. I am worried that the guy is not quite what he seems... he was apparently in the army and went to iraq. He said that he went there when he was 17- is that possible?! He was then discharged due to grief from seeing his friend die. When they started talking he was apparently a prision guard, however he has now given that up and has a job on the tills in asda near where she goes to uni. I am worried that he may have been lying about his past, but I might just be being paranoid. Does it sound likely? Also he has very little money. I have lent them money on several occasions, but they still seem to be able to afford cigarettes. Am I being taken advantage of?!! The other thing is that they have spoken about getting married soon, they want to be engaged by the end of the summer and get married next spring. I am very much in support of marriage, but this seems too fast. Also he was engaged before. He got engaged at new year and it ended a few weeks ago. I found this out from viewing his online profile on a social networking site. One day the three of us were talking and she mentioned an email his ex had sent her, saying that he was engaged to her and left her for my friend. At the time I asked if he had been engaged and he denied it. Later that night (I was drunk at the time) I told my friend that he had been engaged and she said she knew and asked how I knew. I told her. I don't know if they had decided not to tell my before because she knew it would worry me, or he only told her that afternoon or what? And the other thing is that she might be pregnant, or if she isn't she is likely to become so as they never use protection. She says if it happens it happens and they will keep the baby. However she is smoking and drinking a lot, so she clearly doesn't care that much about it. I just want whats best for her and for her to be happy. But I hate her lying to me about stuff (which I know is happening quite a bit atm... it's mainly just little things, but if shes lying about the little things she might be about the big things too). What should I do? Should I just leave her to it and accept that it's not gonna change and that this is the way things are going to be from now on? Also, I am worried that I am thinking about it too much! Is that normal?!!

Do you think it's normal?
