My girlfriend has become an escort

My girlfriend and i are both 21 and were both studying at uni. My GF was at the same uni as me and we have been together for four years and at uni for the past two.

In January last year she met a new group of girl mates whilst on a night out and she soon stopped seeing her old set and went solely out with the new lot. I noticed a change in her, she became more confident and started to dress sexier, which i was fine with because she seemed happy.

A short while after she told me that three of the girls were escorts, which explained why they had so much money all of the time. I nervousily asked her at the time if she would ever do escorting, and she told me categorically, no.

In August last year she hit me with the news that she was booked in for breast implants, which came as a total surprise and a shock. She went ahead with the op and went to a v large size, and the size shocked me even more but she told me it was what she wanted.

Well after the op she became even more confident and outgoing with her looks and her body.

Then in January of this year she informed me she had been asked to try escorting out by her friends' agent. I told her it would mean sleeping with clients but she said she would only try the non sexual escorting work. I naively went along with it and after her third booking she confessed she had slept with him but tried comforting me by saying it was just a part time job and the money would see her through the rest of university.

But in April she admitted she wanted to focus on being a professional escort and was pulling out of her studies with immediate effect. Since then she has told me she wants a second boob job to go even bigger and i see less and less of her.

Am i right to be worried my all of this? Has she allowed herself to become wrapped up in her new world?

Your thoughts would be appreciated.
