What should do? How can I save this relationship?

My boyfriend and I have been dating for four months with the past month (and going) being long distance. I thought it was all going fine, but the other day he texted me saying that he’s skeptical about this relationship and that he’s having a hard time because of long distance + he doesn’t think this relationship is what he was hoping for.

He says that ending it would be the best for both of us and it’s something he’s been thinking about for a while, but I don’t want to. I want to save/continue this relationship.

It’s been about a day since he brought this up. At first I was like I see this as a part of long distance and I’m just not used to it to which he was like you keep saying you’re not used to it and I’m getting tired…

For context: The first 3 months of the relationship we saw each other quite often because we went to the same school (in MD) and even lived in the same apartment building. But then I graduated and returned home (in NY) and he’s still in MD because he has one more year until graduating. And now this past month has been long distance.

I’m just kind of dumbfounded because in the beginning I seemed like he was the one who liked me first/more but now I feel like it’s kind of the other way around.

To add more context, this is my first relationship (not his) and I’m pretty sure he knows that. Like there’s a first for everything so I would think that would justify the fact that I’m not used to things (cuz I have no experience).

For now I sent a long message explaining how I feel, trying to sound hopeful and saying that I still believe in this relationship, but he has yet to read/respond to it (which I get). I tried asking him if we could talk it out through call, but he was like not now, I don't know what to say + he feels suffocated.

I’m just gonna give him space and hopefully time does it’s thing…

Thinking about it, people were right in saying that I should just end it, forget about it, and move on. I think I was just digging my own grave by trying to save it and sounded desperate and pathetic. Like someone told me, there’s no use in resuscitating a dead fish lol…I may not have acted in the best way but it’s too late to regret and change things. The past is the past. There are many fish in the sea…

Thanks to everyone who commented and slapped some sense into me. I definitely learned things throughout, even if I failed to acknowledge the truth earlier. Now I am realizing that there were subtle red flags/things I should’ve been aware of along the way. I was dumb for trying to hold on to an already dead/hopeless relationship.

I just find this whole situation ridiculous/dumbfounding and I’m disappointed at myself for not being able to handle this in a “cool” manner lol.
