So the reason I want to start nun mode begins with this guy I started seeing 5 months ago. We broke up because he entered a relationship with me too hastily after a previous LTR ended and needed time to recover from that breakup and be single, but we still love each other. We still talk every day and are friends and love each other and flirt to some degree.

He says we may get back together but not to wait for him. Thing is, I can't really help but wait because he's my first love. So I was thinking that while I'm waiting, I might as well level up my life. I have mental health issues, a shit social life (which makes me too reliant on men), a poor diet, and probably don't take care of my appearance as well as I could. I'm not ugly, but I have a really good base and don't live up to my full potential I think. So I'm thinking about going nun mode while I wait so I'm not wasting time, and even if it doesn't work out with him, I've made myself better.

Does this sound like a solid idea or am I misguided? Also, how should I go about nun mode. Does it basically just mean "don't date and work on yourself instead"? Or is there something more I'm missing?
