HEALING AND WANTING TO MOVE ON...

At this point in my life, I want to move on and away from HURT! But sometimes I feel I can't and it makes me angry.
It's sad to say, but I equate certain people with the word HURT! What's more uncomfortable about my life is I have to "co-parent" with my HURT for the rest of my life and I don't want to. When I left my ex-husband, I was six months pregnant and done...with no regrets. But I wasn't as ANGRY with my ex than this man now, I just don't want to be bothered anymore.
How can you heal after a blatant offense if the person refuses to leave? I never knew men used children as pawns, I only thought women did that kind of mess. What's even harder is when you were "FRIENDS" with this person and they really weren't your "FRIEND!" I considered this person a "FRIEND" but then I realized, "FRIENDS DON'T BETRAY EACH OTHER"  not to the magnitude I was BETRAYED! For years, I questioned the loyalty of his FRIENDSHIP and I was right for being DOUBTFUL. I never question my gut, I just don't...because nine times out of ten, I'm ALWAYS RIGHT! The only thing I want in my life right now, is to be alone so I can heal. I don't want to live with anyone, sleep next to anyone or have sex with anyone for a LONG TIME. Once again, it is time to FIND ME! I just want to be HAPPY again and find HAPPINESS within MYSELF. I don't mind being alone or celibate. Especially, when you get tired of someone...How do you get them to realize, what they broke cannot be fixed, because I don't want it to be! The choice you made, is the choice you deserve to live with and that's all. Why stay around and pretend it's for the children, when you can just move out and parent from afar? Find a woman who will accept your children, plus the one you fathered on the outside and move on. When you've done wrong, own it and be adult about it and just move on. It's not worth causing someone pain, because you made a decision you CHOSE to make. I've dealt with so much loss, it's time for GAIN in my life. I want to GAIN MY HAPPY BACK....and COMPLETELY! I cannot LOVE someone I never LOVED in the first place and I cannot FORGIVE someone, who doesn't consider my feelings and give me the one thing I ask for and that's SPACE! So how do you heal, when a person doesn't see the need to let you be?
