Me and my boyfriend have been together for a year and 3 months. We love each other very much. We are faithful to each other. Lately the phone calls have been becoming shorter and he doesn't text like he used to. He works as a CNA. He is very busy with his parents and work.

When I tell him that I miss him he doesn’t respond to me. He always tells me that he loves me. I am just so afraid that he is going to dump me. We don't always talk about the future. We really don't talk about the future like me used to. I know that he loves me and that someday we will have kids and get married. I need your advice. Do you think he will dump me?

Try talking to him about it. As you said, he's busy with his parents and work. Maybe he's just not got much time right now. I can see why you think he might dump you but don't jump to conclusions yet.
Can I ask, how long has he been acting like this?

I know that he loves me and that someday we will have kids and get married. I need your advice. Do you think he will dump me?

You've lost me. You claim that you know he loves you and that you're going to have a future together... yet, you are wondering if he is going to dump you.

Well, first, there is no way any of us can know if he will.

Second, if you guys are going to be married and have kids... and you yourself said that you're sure this is going to happen... how will that work if he dumps you?

I sorted your paragraph into 2 parts.
The Dream:
We love each other very much.
We are faithful to each other.
He always tells me that he loves me.
I know that he loves me and that someday we will have kids and get married.
The Reality:
Latley the phone calls have been becoming shorter and he doesn't text
When I tell him that I miss him he don't respond to me.
We really don't talk about the future like me used to.
Do you think he will dump me?

I think that unless you two TALK to each other about what changes are going on (and changes are normal as you settle in with each other), then the relationship is doomed, regardless of who does the dumping.

Thank you for all of your advice but I have good news. He is never going to break up with me. He loves me too much.
