Puppy love stage gone?

[sesrin66]

So, to completely explain this so you guys understands. I've been dating this guy for a year and a half now, and we had something good until he had to leave because he couldn't stay in this state for a certain reason, so he had to go back and live with his family while he got back on his feet. He lived there for half a year, and we made that long distance relationship work. And he finally came back, this April or May, the middle of the month. And it was like that puppy love stage for a bit, and then it just seemed to go to a normal relationship. Except a few weeks ago, is when it started. I haven't really wanted to see him as much, like I've wanted time to myself, the sex drive has been gone, I don't know if it's because I have a new job, and I'm just exhausted all the time or what. We don't really kiss or make out as much. I'm not that excited when I see his car at my place anymore. But, this is my first relationship, so I don't know if this is like me falling out of love, like there is nothing there. Or if it's just the fact the realtionship is growing. Should I definitely break up with him, or should I give this another try? Is this just the relationship growing or is this the end? Info on us: I'm 20, female He's 22, Male, obviously. And we've been together a year and a half now.

TLDR; I've been in this relationship for a year and a half, we had to do long distance for a bit. And now it feels like love isn't there anymore. Should I definitely break up with him, or should I give this another try? Is this just the relationship growing or is this the end?
