Never Can Do Right!

So I have been trying to be in good accords with the ex and it seems like he will not allow us to go in that direction. Every time we start doing good, he finds something to make an issue about. Since the separation, I have stayed low key but it seems like I am the one causing him great grief in whatever I do. This week he was fine and then once he found out that I was having a BBQ with friends at the house, it became an instant issue. He can continue with his life with no problem but I must stop everything and be a homebody. Throughout our marriage, he never liked my friends and was always so nasty to them. Of course, it was all in my imagination and it was ALL my friends causing him harm. I remember no matter whoever of his friends that would come by, whether I cared for them or not, I was always cordial. I rarely invited friends to the house for this simple reason so I am enjoying being able to have functions where my friends are here with me. The 21st 21st will make two years since the separation and they say its gets better....I am still waiting!
