Are you serious?
This is really hard to figure out, you use no punctuation marks and you write in text.
Leave the boy alone. He sounds like a player.

First it is hard by your writing style to believe you are over 13, so it is hard to believe you are 18.

We require real English on this site, not text speech that sounds like a child.

Next you don't live on Facebook, don't worry about what is posted there, and don't worry about what others post on it, they could easily want to cause trouble.

Too many couples live their lives on Facebook without understanding real relationships

So my suggestion, you and boyfriend close Facebook, don't open I up and live real lives

So what are you doing with him?

Not too bright I would imagine.

Im sorry that's how I write

I don't want to mess up 4yr

If the 4 years where not even good, what difference does it make? You're going to put up with a player cause you don't want to mess up 4 years? Get real girl!
When you post, don't text. (it is against the rules here) It is too much trouble for people to have to figure out what you're saying before they answer a question.

I dnt wana mess up 4yr

This is the point of view that is going to waste you a lot of time and put you through a lot of crap. Grow a pair and stop being so naïve.
