Keep in mind this is only my opinion.
It is possible for a 14 year old to have strong feelings for somebody, but I would say that at that age, love is very unlikely. I'm speaking from experience. When I was your age, I thought I was in love. The thing is, though, that you have not grown up and experienced a lot of the world yet; what it's like, what people are like, what is REALLY important, etc. I'm 19, and I have just recently actually started to see what the world is. When you get to my age or my maturity, you will see what I mean.
So, until you've discovered all this, it is impossible to know what to look for in a person, what you want, what is important to you, etc. I was 14 and thought I had my first love. Now I look back on it and rationalize that he was nothing I needed or should have been looking for.
Hope I helped! If you have any more questions, send me a message or add me on facebook or whatever. :)
