Oh Coly, I hate to see this cycle. It keeps happening. You reach out in a friendly gesture, he reciprocates with a friendly gesture, but his sends you spinning.
Your extend your friendly gesture hoping he can see what he is missing. he extends his friendly gesture without the intentions of it being anymore, and it upsets you and rightfully so. "If he can do husbandly like things, like take care of an electrician, why can't he just be your husband!?!"
Correct me if I am wrong, but when I was still attached, that's how I felt. It's not wrong. It doesn't actually feel good when you are still attached.
It seems to be how he operates. Doing these things for you probably absolves him of guilt in his eyes.
So, I guess you can stop with the friendly gestures which you hope will lead him home, or you can take them for face value along with his reciprocations, or you can kindly tell him you have everything handled and you would prefer he doesn't do it for you.
There are options. You need to find the one you are comfortable with that won't send you spinning.
And maybe he never gave you a reason for leaving because it has nothing to do with you? Just putting it out there.
