As far as pushing this forward with relationship talk, you'll know perfectly well when it's time to begin with that.
She will bring it up.
Until then, it's off the table.
Consider it part of the deal you made to possibly get another chance. SHE drives the relationship deal for now. Obviously you don't want this being the case forever, but I would say it's still early in your "changes", and pressure from you in this area could easily be what leads to, as FG described it, "things going south in a hurry."
The seque into some partially separate life is going to be a significant one for you I think. If indeed you have made her feel guilty for "having a life" outside of you in the past, she has learned to be cautious when spreading her wings. The new you needs to show her that you are comfortable and ok with her being completely who she is, life with friends included.
There is still an enormous upside in the way things have been going. You really need to NOT lose sight of that fact.
Continue taking opportunities to engage in your own activities, such as working around the house, etc. I would refrain from anything that smacks of "the old man." Again, in reference to FG's comments about things turning south, your wife is well attuned to your old habits and behaviors. I think if she begins to see them emerge, you will see a sudden and significant change in her behavior towards you. And likely an increase in the talk about no future.
Patience and consistency are your strongest tools right now. When you feel bummed about a lack of positive future type feedback from your wife, throw a bit more energy into strengthening this new man that you've become.
Hard work my friend. But very rewarding as you see that you are successfully changing in ways that resonate with her.
Small steps will accomplish your goal just fine. Again, patience and consistency.
Blessings,
Bill
