Jennica, that's the million dollar question for so many posters here... will this person ever unblock me? If I ever figure it out, I'll share my $$$$

You'd like to handle it better, if you ever get unblocked. Jabiru shared a good link (on "don't enable"), and moving forward living a positive life also positions you healthily for any contact in the future. You want to be in a stable, healthy, calm place so you can respond instead of react to potential contact.
Validating questions are a great way to engage while slowing the pace. Validating questions are questions that are typically open-ended and allow the responder to share how they really feel or what they really think or did. Validating questions don't "trap" the responder into an answer or impose the asker's beliefs of "how things should go" on the conversation.
A "trapping" question might be something like "Didn't you feel so sad when you heard that?" See how the "correct" feeling is built in there?
A validating question might be something like "Oh wow... how did you feel when you heard that?"
Validating statements/words/body language/sounds are also a thing! Though perhaps more difficult online. Examples could be (imagine these with a warm, caring tone, and body language engaged):
Oh wow...
No way...
Yes...
Uh huh...
And then what happened?
And then what did you do?
Oh my gosh...
Mmmmm...
Ugh... (to a complaint)
...
These responses leave the door open for the responder's genuine thoughts and feelings, regardless of what you think they should or shouldn't have said/done/thought/felt. They can create a nonjudgmental space for sharing and keeping the "emotional temperature" down.
Could be worth a try as you consider learning new skills!
