Just for the record, people (not just men) usually do NOT change. People are what they are, even if what they are is selfish, lazy or even a drug addict. Chances are most people are NOT going to change themselves to suit another person's image of what they should be.
If the person you see isn't what you want, move on, chances are high that even if the person WANTS to change, they will likely be unable to sustain the change long-term.
I never changed. I was rescuing critters as a small child. I've always rescued critters, and I've always had critters in my life. When I first met my ex he had to tag along on a rescue mission I was working on (someone dumped a litter of kittens in the local park) to get a chance to spend time with me so ..... HELLO! what part of CRITTERS ARE MY LIFE didn't you understand way back then? So when my ex tried to change me to suit his expectations/desires (no critters), we butted heads, repeatedly. No, I was not giving up what makes me whole ....... I am sure he was surprised it was critters, and not him? I'm not.
There is one thing to be said for being older and wiser, we now know what we DON'T want.
AGAIN if what you see isn't what you want, NEXT!
