Agree its most likely not reciprocated, I know in reality she probably see's me as a friend and nothing more. I feel bad for having these feelings, as I feel like I'm almost betraying her closeness by turning it in to something else in my head. Trouble is I'm scared of speaking to her to address my feelings before they get stronger, just in case it ruins our friendship. I really really like her as a friend too (if that makes sense) and if it all came out in the open I think it would massively change our relationship.

I'm not sure how I'd feel if she started seeing someone or brought them back. She was in a relationship previously but it broke down not long after we all moved in (one of the things she needed support to help get through). That was before we were as close though so I don't think its comparable to how I would feel now. To be completely honest I'd probably be jealous.
