Try to calm yourself. It doesnt do you any good to get yourself so upset.
I know how hard it is to see it played out in public. But, just remember who you are. Remember that you have absolutely nothing to be ashamed of. That's all his. Let it be.
You hold your head up high. You go to those games looking fine and if he sat where you usually do, put yourself somewhere else. But do it as if he is just someone to feel sorry for, ya know?
You be your best self. And if you dont want to talk about it with people, you tell them so. A polite, I'd really rather not talk about it, is all you need to say.
IB, I know this is hard for you but you can do this. You just have to have the right mindset.
One time, h came to an event of our son's. He acted all high and mighty. I just did my thing. Laughed and enjoyed myself and paid him no mind. In the end, he just looked crazy and people were shaking their heads at him. LOL!
Comes back to you feeling comfortable with who you are. Let him blow in the wind. IB is too busy having a life to worry about some fool and where he is sitting, right?
