You might just be picking up on her jealousy of you, and thinking it is your own. We often pick up the thoughts and patterns of thinking of those around us, or those who are directing their energies our way, and unless we recognize when it is or is not our own thought processes, sometimes it is easy to think that what we're going through may not even be our own shit.
Don't let yourself get caught up in any melodramatic thinking nor feeling offended - that won't do you any good. Just clearly state what you want, and be as present as you can be with what is happening. When one is present in the here and now, then anything life throws us will be handled appropriately. But if you're dwelling on negative thoughts or stuff, like taking offense at something, you will be stuck in your head.
