Do I text first?

I’ve been talking to a guy for about two weeks now, through text (we matched on bumble). Things seemed to be going well at first, but recently, I found out there were some negative things being said about him and his startup online. I brought it up to him because I felt like he should know, and it really messed with his head. Since then, I’ve been doing everything I can to help him get the posts taken down, even though they’re not my responsibility.

Here’s the thing: I’ve been the one initiating almost all of our conversations lately, he texts back quickly after but still. Last night he texted me saying I’m an angel and that he’s so thankful for me. I didn’t know how to respond to that, so I just gave it a thumbs up. He also told me we would talk today, but that didn’t happen. I’ve been left feeling ignored and unappreciated after putting so much effort into helping him and keeping the conversation alive. On top of it, he compliments me like "you impress me"

Now I’m stuck wondering if I’m supposed to text him first again or if I should just leave it alone. I don’t want to keep chasing someone who isn’t matching my energy, but I also don’t want to seem like I don’t care.
