Good to hear from you! It sounds like you are making progress on the detachment front. It's nice to be at a point that you really don't care what your WAS is doing. I will say that it is a process that is far from linear, there are ebbs and flows, so make sure to cut yourself some slack if you struggle.
Living alone is definitely adjustment. There is a richness in sharing experiences, both joyful and difficult, with someone else. However, I think it has been an important step for me. Learning to appreciate the silence, to sit with yourself, to find your own joy. (Maybe not as much silence with a little one!) I think it is easier to find a partner when you are already enjoying a rich life and have something to share with them.
In terms of dating, you just need to listen to yourself, don't force anything. I think it's a great step that you are looking around and seeing the various options around you, from the distant European guys, to the quiet dad in your building. Who knows if anything could or will work out, but the more you open yourself up to the possibilities the more you create possibilities. Have fun with it!
