So, I made a friend online sometime ago on an app called Vent. She is from Alabama, and she is a devout Christian. We used to talk about random things all the time, but now I barely get a reply from her. That is unless I am feeling sad and I tell her that, than she is suddenly very interested and starts to help me feel better, behaving like the best friend you could ask for. Once I start to feel well, she goes back to barely replying. I do not understand whether to move on from this friendship or stay in it.
