When I was depressed, I would over-react about many, many things, and jealousy was something I occasionally would come across. Not that I was upset she was hanging out with anyone in particular, but moreso that I thought she was so happy with everyone and I was just an absolute mess that couldn’t even make myself happy, let alone someone else. It was completely unjustified, and she understands why those things happened and doesn’t hold it against me, which I’m incredibly grateful for.
So now that we’re both in much better places, no, there is never any jealousy. :) We know what we mean to each other and we’re very much committed to this relationship, so there’s nothing really to worry about.
