For the jealousy possessiveness thing... You are not cut out to date a camgirl. Not a camgirl in work, and not a girl who has cammed previously.
It takes a certain sort of woman to take up camming. It takes a certain attitude, a certain amount of confidence, sexuality and independence. These kinds of women have a lot of incredible qualities, but they are not the sorts of women who merge very well with men who are prone to jealousy and possessiveness.
Some girls like jealousy and possessiveness. It makes them feel loved and cared about. They like the drama and they like the attention. Those girls often like the idea of feeling "owned", not as in a slave sense, but as in they abide by their boyfriends feelings. These girls aren't camgirls. A camgirl can pretend to be like that, and she may have parts of her that are like that, but she has taken a step into a job which a girl who is truly like that just wouldn't be able to take.
One of the things I like what I do for a job because when I was single I could ultimately see what a guy was like when faced with the situation. I am a very outgoing, flirty, friendly person, I also am fairly good looking and have large boobs. I get a lot of looks and come ons. I could not go out with a man who would have a hissy fit every time a man eyes up my breasts or tries it on with me. I also want to go out with a man who respects women whatever they do for work. Me being a camgirl was the ultimate test, you can see pretty quickly what a man is going to be like from how he reacts to that kind of job. Most men's reactions weren't as chilled as my boyfriends reaction, and most men aren't cool with the idea of their girlfriend doing sex work. I am now in a relationship where I don't have to worry about my boyfriend getting jealous, possessive or controlling, because I chose someone who didn't have those things in his nature, sure they're there, as with everyone, but not enough that they'll ever be a problem.
You are not one of these men. You are a regular guy who shouldn't be dating a camgirl. You may one day have different opinions, and you may change, but for now you cannot force it.
If everything goes well with you and her, what will she do? Move away from her family and home and live in the UK? How will your friends treat her? Not only is she a camgirl, but she's also Romanian, which although I doubt she'll get racism from people, there will also be a big culture shock, things will be difficult for her, she'd have to start over. She's not a native english speaker which makes it harder to get jobs, and I don't know how she'd been educated, but there'll be different standards in Romania to the UK which might find getting work harder. You don't earn much money, and her money will not take her as far in the UK as in Romania if she continues camming, if she doesn't she'll be earning even less.
I think although online relationships sometimes go well, the ones that work are slow burning things, ones where it takes a long time for the relationship to develop.
It is VERY easy to fall in love with someone you meet online. You only see what they want you to see, and they only see what you want them to see. You then fill in the blanks with what you want to see. You spend long hours talking, which seems amazing, but it's really because the human mind processes time spent at the computer differently than in real life. Ever noticed how you can spend an hour on facebook and it feels like barely 5 minutes have gone by? Ever noticed how hours of your life can drift away in front of the laptop and it feels like it's been no time at all? That's because your mind cannot work out time in the same way, meaning you get sucked in. It's the same when you spend lots of time talking to someone.
It then also becomes addictive. You never really get what you want, you never get release, you're constantly curious, it's always a mystery, so you want more and more.
Your mind has created your dream woman, and she's done the same for you. Even though nothing in your relationship is actually right you're clinging onto it, trying to force it to be right, because your mind told you that this is the girl for you. She said certain things and you filled in the blanks. Your relationship is a fantasy. It is less real than the relationship she has with her paying regulars.
There aren't that many camgirls in the world, though the internet is full of them. There are thousands and thousands of girls your age who don't cam, strip, have sex for money, who will simply be a girlfriend, girls who live in your country. What they won't have that this girl has is the same mystery, the same drama. They will also be real rather than a fantasy, you won't be able to imagine things about them, see what you want to see, because you'll actually be with them.
At the end of the day though, fantasy is great and all, but reality is where it's at! You can fantasise about the perfect girl, imagine she's real, but she's not. Don't pursue this. This girl lives in a different world to you, there is no point in pushing it. You should never have to force a relationship.
