I guess I just feel like my partner does it to make it out like I'm some mean, angry person, who has a problem/gets mad at any/every little unnecessary and trivial thing, when I don't.

Like, with the examples I gave, (not the only instances just ones I can think of currently to give a better idea of what I mean) she'll just simply look at me and then apologize, or if she accidentally slightly touches me, or asks/says something after I reply she'll apologize, when I never even give her reason to think that I'm upset or bothered or anything by whatever she does that she apologizes for.

And to take it even farther, I specifically have, and continue to tell her every time that I'm not upset or bothered with or have any problem with whatever it is she says sorry for right after, so she knows that I don't have a problem with it.
