Hi niceguy, I'd say that there are going others out there who are going to care, who are going to be there for you, who are going to respect and share your wishes and your feelings...........without needing to change, because that is who they are deep down.
And this person.............well you have worked out that they aren't what you want/what you need in your life............it might be that they don't want to change, it might be that they can't change, it might be that they just are who they are...........but they just aren't someone you need in your life.
Now........I'd like for you to be keeping those standards for yourself, OK??
The recognising you need more.....you need to be treated better than.........you don't need to be putting up with.......I'd say you've been hurt enough, right??
And you know there are really caring, genuine people out there.
