I think that you feeling sad cause of him not talking to you or communicating clearly is totally valid. He might be busy, but that is not a reason to ignore your texts/emotional needs. That doesn't mean he have to take care of you all the time, but he can definitely try to communicate about it ^^
I want to remind you that confrontation doesn't have to be a fight, it can often turn into a fight when one party turn into defensiveness or not being open to an assertive discussion due to emotions, but it is not a bad thing to do. Definitely try to talk to him, you can start with things like "Hey, I want to talk about something that has been on my mind lately. Recently I've noticed that you have been leaving me on read more often. I really feel upset about that, if you need space for yourself, you should let me know instead of ignoring me. If there is something wrong, please let me know and we will talk about it"
You don't have to copy that though, it's just how myself would word it. But the idea is you would just let him know how you feel about that and that you hope you both can talk/solve a potential issue
