Disappointed by a Few Online Friendships

I don't think checking to see if she's ok is necessarily enabling. You could maybe send a message saying "hey, just checking in to see if you're ok." The issue is if she says no, then she might expect you to listen to her vent or provide advice, in which case you'll be forced to either ghost her at that moment, state that you'll no longer be providing your services or end up doing the opposite, and that is what could be considered enabling. Even if she says shes fine, she might wonder why you haven't been messaging. You can either explain yourself or again, ghost her at that moment.

None of the above would be ideal I assume, since you'd rather have her reach out to you. Speaking of which, what will you do if she does?
