Frustration

I'm going through a breakup. He's a great guy, but despite being a 38 year old father of 5, his need for constant attention and his thoughts on appropriate boundaries with other women are rather immature...so we broke up. I presented my concerns and the pain his behavior caused and he made it clear he felt no need to change for the sake of our relationship. I know he'll change eventually...but it won't be for me. But I think what we've gone through and how I have been able to become vulnerable rather than defensive...I think I got in his head and slowly...maybe...he'll realize he needs to change for the next girl...honestly I just feel that he is in love with love so he told himself he loved me, believed he loved me, but the whole time his actions were not as supportive of that belief. His subconscious was not on board with our relationship. I remember the first time he called me "babe" as a pet name...I don't remember him using it again. Though I picked it up and regularly used it, those sweet little things were not consistent from him. Anyway, this is a picture of my frustration. It's visual rambling. It goes on and on, weaving in and out of itself, but not going anywhere. Sometimes I think I'm unraveling the mess maybe by continuing to think about it...but maybe I'm not. Maybe I'm just making it worse...because at the end of the day, reality is that he and I are over. It's not necessarily even that I want him back. I just have all these emotions that I have to find a way to deal with...work through...embrace...accept. The hurt and the anger weaving around...going nowhere. SO, I want to try to NOT entertain these rambling thoughts that go nowhere and accomplish nothing. I need positive thinking, productive thinking...and constructive thinking. It's easy to see what he needs to learn for the well-being of future relationships, but what do I need to learn from this? That's the truth I really need to unravel. That's what matters.
