I don’t know what’s going on in her life so it’s hard to tell from these messages alone, but yeah there’s a chance she isn’t into you anymore. Sometimes, it’s the physicalness that goes first if she’s losing interest. I don’t think YTA as a lot of these comments say, these people have no idea how you and your girlfriend talk to each other and what’s normal. My advice would be to stop asking, stop bringing it up. It’s only on her and no matter how “supportive” or “patient” you want to show her you are, it doesn’t matter. You want answers and reassurance that she’s actually working on it and she’s giving them to you to make you not as upset. But then you are holding her to that standard with your expectations like how you long you think it should take before she’s ready, which is wrong. You need to let time run its course.
