I am so sorry, @Flowercandy, but you are absolutely hooked on this man and your interactions with him.
If you are really not infatuated, then you need to stop completely - block his feed, block his number, stop watching him (or other streamers), no more live chat. If you need to find real-world help to beat this addiction, then please try to find it, but you need to see what the rest of us are seeing - an addict who says “Oh, I can give it up any time I want. I hardly do it at all, I can ignore his calls” etc, etc.
I realise you don’t want to hear this or acknowledge that there is even the smallest chance we might be right, but we are. P,ease stop all interaction with this man, including watching his stream - do it for some weeks, and then see if that space has allowed you to get more clarity on this situation.
Spend your time and money on your child - that is the most real and most important relationship you have.
