Why is he avoiding my question?

I've been seeing a guy for 7 months and I'm I. My late 20s he is early 30s. I have always felt like he has walls up but still felt like he really liked me.

I find the biggest issue is when I try to have more serious conversations about where things are heading or his feelings in general he gets overwhelmed and almost has a panic attack. I feel like I get vague replies.

On a normal day to day he makes an effort to contact me see me etc but two nights ago I confronted him via text as I won't be seeing him for a while to just get some clarity.

I explained that I have been thinking of us lately and know it's an uncomfortable topic but I need to know what direction this is heading. I asked him if he was wanting to commit to a relationship. I explained that I need a more serious commitment and if he accepts all of me including my child etc.
I also said it's ok if he does not a want the same but I need to know where I stand.
It took him nearly 20 mins of leaving me on read to just say, he knows I'm gonna think he is making an excuse but he is really tired and has been in and out of sleep can he please talk with me tomorrow and sent a kiss.

The next day he waited until the late afternoon to let me know he has to go to some emergency work meeting and that he has not forgotten about me.

And now day 3 still nothing at all.

I am unsure if he really just lost interest that suddenly or if I should not just assume but I find it a bit hurtful and rude like I'm not a priority.

Ps he was the one that has been saying things like he sees himself with me, he really really likes me, he is 100% sure about me etc.

I just can't understand why he just won't answer me at all especially since we have been seeing eachother for a while and even if its a no I feel I deserve that response
