College long distance

my boyfriend and I are both freshmen in college. We have been dating for two years and it’s been great. The first month and a half of us at college was really good actually, we were excited when we got to talk to each other and so so in love. It’s seemed to die down. Shorter responses and less exciting conversations. I dont know if this is normal for a long distance relationship because it’s not as new or if I should keep an eye on the signs of us fading. I love him and I know he loves me, but sometimes it doesn’t feel like he’s super into it. I’ve talked to him and he agrees that the short responses aren’t good and we both are not a fan of them, and agreed to work on it. He hasn’t really changed his length or interest into talking but I have been working hard on it.

We FaceTime almost every night and it’s normal and fun and happy. Just the texting isn’t always the best..

Is there a problem arising or is this normal for long distance ??
