Getting back to regular programming

I have been undoubtedly depressed and angry. With some adjustment to my medications, I am feeling less angry and more depressed. I have been reading this book called "He's just not that into you." It seems to be insightful in a weird sort of way. It makes me realize some things that I should have not been putting up with for a long time with Buck. It also confirms that once a cheater, always a cheater. Which I did not even consider to be an option any longer. I absolutely could never be with him again. There is no trust and I have no respect left for him whatsoever. He calls trying to make me feel guilty about Luke. But, I am very adamant that he does not have the good qualities that need to be modeled for Luke. Buck is just trying to make himself feel better and at this point I have no consideration for his feelings. He certainly was not thinking about me or Luke while he was cheating. I am very hurt, but know that I have to get past this and I will. I don't know if I will ever fully trust someone again, but I know that currently, that is the last thing I am thinking about. I don't want another relationship. I don't want to open myself up to be hurt again. I just can't.
