Actually he was never in a relationship with his childhood friend, he just once previously stated that he liked her the best between all the others, though it's currently uncertain if that is true for him now.
Also I get the last part about not being able to call him a loser because I mean because think about.... He suddenly, out of nowhere, gets surrounded by all these cute girls who are constantly throwing their sincere feelings at him and being especially kind and caring towards him, a guy who has hardly done anything for them to care so much about him, so you can't really blame the guy for having a hard time choosing between them while also wanting to find a way to somehow repay them all. I mean put yourself in his shoes
P.S. This here goes for all harem protagonists.
