Thoughts please ?

So this has been going on for a few days I would text my bf and he would read my message and just sometimes don’t respond for some certain time period. I’ve try to ask what he was doing etc even prior to these images and sometimes he answer nothing much so I don’t know if he’s driving or not. Sometimes I would ask if he’s okay ? etc he would just ignore the message for some reason I’m not sure why so I got fed up regarding these two things and wrote “don’t know what I did to you for you to constantly leave me on read….” It’s just hard because I’m so open with him he knows everything that I’ve been through, he knows when I’m at work etc, he knows if I’m home or not etc but it sometimes feel like I don’t be knowing what’s going on, on his end because he doesn’t tell me and if I don’t ask I wouldn’t know. I just wish he could be a bit more open and communicate to me more I wasn’t trying to hold anything over his head. If there’s something bothering me and I say something he always gets upset. I try bringing this issue up the other day and he ignored me. This was a result of saying something today. Was I wrong for what I said or how I worded it things ? Please let me know. Also he recently change his number and didn’t give me the new one until I basically asked for it so we’ve been texting on Snapchat prior to him giving me his new number. Idk the communication sometimes from his end I don’t even know how to explain it.
