This is all sounding amazing!!! You might need to be a bit careful with the ladies, despite the ring and the obvious connection...haha...but still it looks like you are enjoying yourself so much more, which is great..! Sometimes a third party doing the smallest, simplest gesture can give us a lot of reassurance but can also remind us that when we put in the work it pays off! It might take some time...haha...but it pays off! I would say though instead of trying to figure out what it is that other people have noticed--because it might be all the things you mentioned and much much more--try to focus on what it is that you want to work on more...I mean for everyone of us, there is a special thing we like about Tango...one thing that interests us more than the others. I think if you slightly shift your focus towards that, the change and the progress you are making, might be more obvious to you..!
