Thank you to all the people that commented on my original post. I appreciated the insights that were given. I didn't know Ella's bfs stance on the matter so I sent her a message about it because I knew that they were hanging out before Ella and I were getting together that afternoon. When ella came over, we talked about the whole thing, apparently he's a little awkward uncomfortable but that's just because he generally doesn't like pda and not because he's jealous or anything. Ella says he doesn't mind the way we've been interacting. We have decided that even though many people disagreed with the fact that it's all platonic and good fun it's okay for us to interact in that way with each other because in the end we need to be able to trust what our partners are saying and if we can't trust that and have open communication and have to read in between the lines of everything they say than it's not a healthy relationship anyway. So given that my gf and her bf don't mind our platonic flirting it's okay to continue to interact as we have been.

On to the actual update. I had Ella over this afternoon to watch a show together and we were talking and she was mentioning how she would like to live in the same area that I'm in. I'm not sure if my current housemate wants to continue the lease next year and he might move out and Ella mentioned how she really likes my place and surely she should just move in. We used to live together but the place was awful and she thought she didn't like living with me but after moving to new places she realised she just didnt like the house and wasn't coping well (it didn't have any windows and neither of us were particularly mentally healthy) I think we would have a great time living together next year. My gf has also floated the idea of living together so I don't know what's going to happen in that regard but I guess it's a problem for later.
