That makes sense. I used to be the last to leave at a dinner. Talking for hours with friends and reluctant to part. I drank very little tbough as I am a cheap drunk. Now though I'm ready to go home first. I find I'm just ready to be home and relax. Yes. Cancer treatment has certainly changed me. It's changed my energy.
With all couples life sometimes gets out of sync with our direction. It's important to have conversations around this so you don't end up resentful every time you go out. It may well be he wants life to go back as it was...for us though, we are forever changed and feeling safe and happy in that changed life takes time.
