Let me talk about how it's so interesting that John seems to have great people skills yet talks a lot about failed romantic relationships. And his fixation on romantic relationships themselves.
Now bear with me here. And this does mildly pertain to an episode that's not fully out yet, so there's vague allusions to that, so just beware I suppose.
I think it's very interesting that he has good people skills, but to strangers. He can talk a stranger down from violence. He can somewhat charm strangers. He's a very good stranger person, not necessarily a very good people person.
We see a pattern in a lot of his close relationships that we're told about (excluding his mum of course) where he seems to try really hard with people he's close to. In the latest mailbag he talks about having a partner who broke up with him on his birthday during quarantine, which then led him to re-enlist in the army (if I remember correctly, he enlisted at first to prove to her that he was a serious person, which also just break my heart because he deserves to be his silly self).
We've (me and a few friends) speculated that the reason for his quarantine relationship failing might've been because he suffocated his partner with affection while still somehow missing something there, maybe it was that the relationship felt forced because he was trying so hard.
I do think it's very tragic how he can connect with strangers so quickly, but he seems to not know what to do once those strangers become, well, more than strangers to him. He's very good at quick connections. He doesn't know what to do with a long term connection, or a connection that gets picked back up (we see this with Hayter in REIG, he feels immensely jealous of this person whose life he saved).
Which puts a lot of pressure on him (from himself) to do Sherlock and Mari right. Because they've stuck together for seven months now? This is another long relationship ride, and I feel like especially with the PTSD, and the general war veteran pain, he would feel the need to prove to them (and by extension himself) that he can get this relationship right, that he can keep these people close to him.
Which then loops back around to his abysmal self esteem which if I start talking about I will never stop so I'm shutting up here. And if you have things to add please do because it makes me very happy when people affirm my rants.
