He knows now that I'm tired of wasting my time with him

I have been verbalizing my intentions a lot today on my Facebook and one of his friends talked to him I think about it. After he got off the phone with his friend, he started being more nice to me and after I got our daughter out of the tub, he got rady for bed cause he's got to get up early for work. Anyways, he saw that I was a little upset and I told him that nothing is going to change cause he won't talk to me and I'm just tired of giving him chance after chance to get things right or better between us and he keeps letting me down and disrespecting me time and time again. 

I'm tired of giving and giving and not getting much of anything back that I want or need. So, I'll just do it on my own again where all I have is my kids cause that's all I really need in life. I'm not meant to be with anyone forever. I'll just have to find a way to accept that once I leave for good. Wish I could've gotten through to him about how relationships really work, but there's no use at all where it concerns him. He is just like the Tin Man from the Wizard of Oz. He didn't have a heart! I almost want to say that he's like all three of Dorothy's friends that wanted something from the wizard. He doesn't have a heart, and doesn't seem to have a brain or much courage either. That is sad, really sad to me. Maybe one day he will be happy and find the right woman. Its just not me!
