Its a good place to be in, piecing. Welcome. But I am a little confused. Did you say your H is still in touch with an OW? Did they have an EA? I think its good you let him know how you feel about it. Just don't bug him, and if one day you have to set a boundary, do so when you know you are reasy for the consequences.
But for now, if you feel you are connecting, then be the best you can be, keep your changes, and let him see how much he will be losing if leaves you. I think what you are doing.... still keeping on the track you are in, with regards to child support, living apart but dating .... it sounds good to me.
One thing though.... don't expect anything! Enjoy it and foster the communication, connection and love.
Keep posting and read the stories here in piecing to get an idea how hard it is!
