You may post wherever you feel most comfortable. Your situation is absolutely fine in the Newcomers section, and would be fine in the MLC section as well.
As to readership and responses, traditionally the Newcomers forum is a busier one and has more response. Although sometimes it does depend a bit on how many other folks are concurrently posting along side you. And how comfortable they are posting to your situation.
Your thread and situation is read a lot. As of right now, at just under a month, there is 44 posts with over 1500 viewings. Lots of folks are following along.
I know it takes a little while for new posters to get their feet under themselves. When you’re ready, reach out to other people’s threads. Most folks will reciprocate; dropping by and offer their views. Like in real life, breaking the ice is often the stumbling block.

(By the way, I’m going out to my best friend’s cabin for the weekend. We are putting on a new roof. So, I’ll be offline most of the weekend.)
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
