>>12344423>friend interestHe's a bit younger? So like, primary school or college age then? Well, even if there's an age gap you clearly have a deep enough bond that it doesn't get degraded by a significant age gap. As for the closer aged one, you mentioned he's rather dodgy and a closed book. First thing you might wanna ask is how does he reciprocate for you? It's possible friendliness might not be mutual, and he just is being polite.
>relationshipAs for your gf being clingy, that's a personal preference. Some people like a constant stream of interaction, others prefer gaps, or at least respect other's free time. But if you have nothing to do there's ways of filling up time that I can suggest.
>ghostingAh, ghosting. This isn't uncommon with even well adjusted people. It's hard to keep up with everything in life when you want your own distractions as well. I've accidentally done it to my best friend actually, with a wave of depression that hit many years ago and lasted.
However, ghosting is not irreconcilable. I reconnected with my best friend even after nearly 6 years of no contact, because I put some effort into researching a connection. Thankfully it was rather easy, given he was also wondering how I was doing in life and I contacted him at a good time, but a friendship likely won't be ruined unless you intentionally ghost. There's a massive difference between unhelped apathy and purposeful avoidance. Do you know what you did with them? If its the former,, and you still wanna reconnect, it may not be too late.
That one dude who mentioned a one-sided relationship yet didn't attempt reconciliation at a low point might've not been as much of a friend as you hoped though. Its ok though, not everyone has to be friends.
