<human>: Summarize the given text in a few sentences.

In short we've only been married for 4yrs but have been together for 10. We probably shouldn't have gotten married in the first place. We had our first child young. She cheated on me when he was 2yrs old. We reconciled and 2yrs later we had our 2nd. After, that we hit another bumpy patch and decided to split. The split lasted for 1yr and then we got back together and got married about 2 years after that. 

As I stated above I know we should not have got back into the relationship in the first place but I really wanted us as a family to work. I now realize that it can only work if both people are working at it. 

Fast forward to now. We are separated. I no longer feel like I need her in my life to survive which was an extremely unhealthy feeling to have and one I know prolonged our relationship. She was always willing to stay because I provided 90% of the finances and I would allow her to keep coming back. I fed the beast per se. I feel bad for her because I know now she will never be happy with who she is with and will always entertain infidelity no matter who she is with. 

My issue is this....I have this beautiful woman inside and out that is really interested in me. However, everything that she does I feel like I find something to remind myself about my ex. For instance when this woman sends me pics of herself my mind drifts to think about my ex and all the pics that she would send to men when we were together that were never sent to me. That is just one example, but what the fuck is wrong with me? My ex treated me so badly and I know it. My mind just cannot turn it off. It's beginning to make me literally crazy and I am wondering if I have something mentally wrong with how my brain is wired. I should not be thinking about my ex when this other woman who is truly interested in me and shows me a lot of affection. I believe it will begin to hurt my current relationship with her. It is not fair to her and I want to give this woman 100%.
<bot>: Cannot get over a wife that cheated even now with a great woman that is ready to be in a relationship with me. How do I get over my ex?
