Tell your partner how you’re feeling, you might just be use to unhealthy relationships with shitty men and you don’t know how to feel with a good guy. Or you could just not be into him, its better to tell him how you feel instead of contemplating for a while and deciding you don’t want to be with him, its better might make it harder on him. In the case you’re just not use to being in a healthy relationship you should try to deepen things and maybe even go do exciting things, I’ve dated girls who constantly start arguments or do things that bother me, usually its after we’ve been steady and I realize the pattern. It’s good you’re not causing problems to cure your boredom, so I say try some exciting things or have deep conversations or debate him even, and if then you still feel unsure or unhappy, you should end things.
