Is it normal to think and feel this way?

I turned 18 half a year ago. I've never had a boyfriend. I have been kissed before, but I don't think I've ever been in love or liked a boy. Also, those kisses weren't really consensual... I feel that the crushes I had on boys were just minor crushes, whenever I think about them, I come to the conclusion that I was just being stupid. A lot of my friends are taken and I see couples everywhere. I'm not worried that I don't have a boyfriend, but I'm worried that those relationships my friends and other people have are not real. Something tells me that most of them are together because they can, or because they want to try having a boyfriend/girlfriend. I just think that they're too young to have a real serious relationship. My view is that you shouldn't have a pointless romantic relationship with someone. So, you shouldn't get a boyfriend/girlfriend without thinking "I'm going to spend the rest of my life with this person!" Because in the end, that's what you're striving to do, right? Find a partner for life. And if you're 15 or 16 and get a boyfriend, you almost know for sure that you'll split up some day. Yet my friends and classmates are still together with their boyfriends and girlfriends from when they were 15 or 16. It's two years later now and I wonder what will come of it, I wonder if they really love each other. The reason I think it's pointless to have a relationship without having "staying together for life" in your mind, is because at some point, you'll get attached to that person anyway and he or she will leave you and you'll get hurt. You'll get hurt bad. And you got hurt while you didn't have to. If you know that you don't want to spend the rest of your life with that person, then why go through all that pain?

But sometimes, I feel the relationships between my friends and their boyfriends/girlfriends are real. They really do care, they really do love. But... They also engage in sex. Which makes me think that they're living an illusion, that they're only together for the sex and they THINK they love each other, but deep down, they don't. After thinking that, I think that I think too much. Yes, a lot of thinking. I don't have these thoughts with older couples though, like age 22 and older.

I have been asked out a few times and I hear that "that guy" and "this boy" like me. I always wonder what makes them interested in me. Either way, I have no intention of going out with them. I might come to like them, yes, but most of them are my friends. I don't want to give anyone false hope, so I don't want to go out with someone I don't like "that way". If I do, I might end up hurting that person a lot and it will be awkward to stay friends. No matter what anyone says, I WILL feel awkward about it, even if the other person doesn't. So, I just want to wait till I come across that person that makes me fall head over heels in love with them and we'll see how it goes from there. I think I do have high standards though. Well, 'high'... There are a few things and I have a feeling they are rare. Like, I want someone that thinks of relationships the same way I do. I just can't seem to find anyone like that. Then, that person also has to be virgin, because just like meaningless relationships, I am against meaningless sex. It's already so difficult to find a virgin these days! And last, but not least, that person needs to be able to be honest to me, trust me, have faith in me and I will have to be able to do the same for that person. But that's only natural, right?

So, basically, I think that romantic relationships between young people (under 20) are fake and I worry that I won't ever find that person whom I can take for who he is. If it's not normal to have never been in love at this age, then I don't have problems with making people fall for me, I have problems with falling in love.

I would like to know your opinions about this. Don't be afraid to comment and add things, I'd like to know your views too.
