Fight over text?

You might try to have adult conversations, but you can only do that if both parties can act like adults, which doesn’t seem like your case

Why don’t you leave a message saying the things you wanna say. And then tell him you are gonna call him and talk to him about the same. This way maybe he will be ready to talk and take your call

You need to have a conversation about this fact and tell him you don’t like doing this over text. You should stop and call him now. you can make a step in the right direction by writing out letters to each other instead. Then show the letters to each other in person.He should be willing to work on this with you, being able to talk to each other about things is absolutely vital to keep a relationship healthy long term.
