How the hell do you break up with someone that is so kind and caring and not feel like a complete A-Hole?

As per title, I (30M) am in a fairly new relationship with my girlfriend (30F). Last night after I left her place I had one of those moments of truth, where I had to confront the fact that I just don't feel that spark and connection between us to take things further.

The problem is that she is so kind, caring and considerate . The whole time we've been together we've barely argued (I know it's still early but with previous gf's there's at least been a disagreement of sorts by that stage). I don't know how to break up with her without destroying her self esteem or leaving her with a toxic view of future relationships (her last long term BF cheated on her). It'd be a lot easier if she wasn't so nice all the time to be honest.

I can tell she's become attached so I doubt it's going to be easy relatively speaking , but what's the best way to let her down gently ?

TL;DR - don't feel connection with gf, want to break up with her. She's really sweet and I don't know how to do it without coming off like an asshole.
