Putting up boundaries

I have a friend that is pretty lousy when it comes to dating. She ended a toxic relationship back in January and almost immediately started another with her long time guy friend. This "new" guy is terrible at communication and will go on trips and not even tell her. It has caused her anxiety to spike and she usually vents to me. I'm 100% fine with my friends coming to me for advice but she messages everyday with the same issues and I finally told her I'm done talking about it and I'm taking a step back. At this point she either has to accept lack of communication or move on (I think this guy is not the best choice but that's her business).

Hopefully she understands I'm still here for her, but we can't keep having the same conversation!
