So I am in a psych ward but am, according to all the professionals here, mentally healthy enough to leave.

A few days ago, we had a new girl join our group. She is a year older than me and needed someone somewhat familiar to get into the swing of things with, and thus I was chosen. And it was amazing. We talked a lot and got to know each other better. She told me about why she was here, I told her why I was here too. It was actually quite nice but I didn't think much of it then.

That night, she said she was too scared to be alone and wanted ME to be with her till she fell asleep. They said that was alright because it was helping her so I sat on the end of her bed and we talked for a while until she eventually fell asleep. This has happened for the past three nights.

All our recreational periods are spent together and we eat together and it's actually so good. She hugs me a lot during these times. I felt uncomfortable with it at first because I'm not used to it but i have started to embrace it and have started hugging back and also hugging first.

I didn't want to give into it at first but I do believe that I have developed feelings for this girl; the first time this has ever happened. I'm supposed to be leaving today but she said she wanted me to stay with her. They said that they couldn't accommodate for the rooms but she said we could share a room.  There are bigger rooms here, so they're gonna put a spare bed (memory foam mattress) on the floor for me so I can be with her.

I have bpd. She does not. However, she does have childhood trauma and part of the reason she is here (relatively recent too) is due to a very abusive relationship; she self admitted due to major suicidal idealisation. I feel like I would like to be in a relationship with her but I'm not sure if I should, or if it's me unknowingly taking advantage, or if it is what she wants (she hasn't mentioned a relationship or anything), or if it will be healthy or good for either of us?

Please can someone give me some form of guidance on this?
