While I don't do IG, there are social media outlets where I have accounts. Forgive me if I am unfamiliar with the algorithms on IG.
I have seen my own Facebook posts/pictures from days/weeks/months back that end up getting responses of some sort. Generally, it is from the same person and in a fairly rapid succession. When I have looked at my own timeliness, I see posts from specific folks that also go days/weeks back. My guess is that there are two things at work here;
A. A father of a newborn having time (and perhaps a sleeping baby) on his hands, so he is mindlessly going through his social media.
2. By "liking" a post/image, it is likely that more (and further back historically) have shown up on his timeliness.
Unless he is commenting, I wouldn't pay attention to the thumbs up being given.
Not remembering your backstory fully, but seeing that you are coming up on a year with SI, I would take this crack at your WH's request: he is feeling the strain. He is dealing with the hurt he caused with his betrayal, he sees the reality of his unworthiness, and is forecasting a future where you have connected with an old friend and end up leaving him. In short...he is anxious and worried. And he should be.
Not because you have done anything wrong, but because he has. He likely doesn't understand that you, as the faithful spouse, aren't going out looking for someone else, ESPECIALLY an old friend with a newborn. He doesn't understand that because he can only understand from his own past. His desires for validation took him outside of the vows he made. So, because that is his framework, he worries and he is anxious.
My wife deals with the same sort of thing. While she has numerous sources of her anxiety, a portion of it comes from her "worry" that she isn't "good enough" and that I have reserved the right to change my mind about the relationship whenever I see fit.
I don't hold that "decision" over her head like a sword waiting to strike, but she apparently allows it to weigh on her every day. Sometimes the weight is greater, sometimes it is less. But that's the lens she chooses to see through (Cap might decide that today he's had enough) because that was the lens she decided to see life through when she jumped into her A.
Just my 4 cents (because that was way too long for 2 cents).
