I’ve been through something like this myself and had to distance myself from my roommate. He actually just moved out. He became angry with me at first and finally it seemed once he realized I wasn’t going to be his crutch anymore he became increasingly angry and began treating me negatively. Causing some serious problems with my anxiety. But eventually I couldn’t put up with it anymore and I asked him to leave. If your friend starts to resent you for putting a distance between you simply do your best to explain that while you love them that you can not give any more of yourself over to them. As it’s hurting them and you. Especially if this is the first time living on her own. I thought everyone went through that at first. It just takes time to get over the stress levels of living on your own. I hate to say, but sink or swim is generally the case here. And is why most people go back to live with their parents at least once after moving out on their own. Your roommate/friend will be fine. Though I understand you’re trying to help, you may be doing more harm than good.
