Hi Newheart,
You should feel anger for the way he treated you. He was using you. You opened up to him your feelings of love. His actions showed that unless you were available for sex he couldn't make time for you. That is no way to be treated. You deserve someone that will take the time to put you first. Yes, we all have to work to survive and have a comfortable life. But he is making work more of a priority then you.
I hope you can see that you are worthy of someone that will treat you better and with respect that you deserve. Keep being strong. Keep taking it day to day.
