Is he still interested or is ghosting/fading out?

So a month ago I met this guy on tinder. We talked every day and after a week he asked me out. We go on a first date it went really really well to the point mid date he asked me for a second one. The next week we go on our second date. That day goes really well too, we take pictures together, holding hands, doing pda, etc. We talked about going on a third date, we decided on a place but we didn’t pick a date because his job was making him work after hours for a week.
We kept texting each other every day, resuming the conversation the next day if one didn’t respond. That same week I had a death in the family. I text him and explain to him if I replied late then this is why and he said it don’t worry I’ve been really busy at work please take time with your family. I didn’t get back to him until 3 to 4 days which was on a Saturday. When I message him and we kept on talking, he asked questions about my family and the funeral. He text me on Sunday but I wasn’t able to get back to him until Monday due to family drama. I didn’t hear back to him until first thing Tuesday where we resumed the conversation. Then Wednesday goes by and I didn’t hear back from him. So this Thursday I messaged him and told him good morning I told him hope he’s OK. He responded back and said ”Hii (name)!!! you’re too sweet :)” and told me that he’s been trying to catch up with work and it’s been really busy week. Then we continue to text until Friday where he asked me how I was doing and I told him i’ve been just keeping busy doing art and working. He asked to see my artwork and he loved it and he asked me a question about it and I didn’t respond to the next day at 6am-ish because he text me at 11pm. I haven’t heard from him yet and I’m starting to worry, get anxiety, and think that the absolute worst. We have been nonstop texting since we matched, the conversations flow, there’s explanation points, smileys, questions. So I don't know what’s happening. Any advice is helpful.
