I don't know why you're offended. If it's the banter, I didn't swear, I'm just enjoying a joke.
If it's the situation, I'm not bragging. After months of radio silence, she now goes from "I love you" to "this means nothing, I need you to leave me alone" in 5 minutes. It's confusing and I need to put it out there and see what I should make of it. Sometimes it's nothing, sometimes it's something I'm doing wrong.
Apologies if you believe this is just me being crude, but it's not.
Resentment occurs when we aren't doing what we need to care for ourselves, though we expect others to do it for us.
