Hello, i am a guy and new here so please bare with. I am 30 years old. I have recently 4 months ago ended my relationship with long term partner and mother of my two children after 12 years. I had found myself being unfaithful to her and no longer felt like I could continue with her after what I have done and I am eating myself away telling myself she deserves better and true happiness. The problem is, she still wants to stay with me. Over 12 years I have been unfaithful a few times of which I am not happy about. I have no attachment to anyone when I do. My long term relationship lacked excitement and we tried to address this for a number of years but my partner struggled to make any real changes. Very early on in our relationship (first year) she had slept with a couple of people during a time we agreed to take a 'break' with intentions of getting back together. That day hurt me bad. And it is the only situation I can attribute my behaviour to or what may have been the root cause of all this. I have since been speaking to another woman who is fiery and much more intense than the partner I am used to. My now ex is such a laid back, submissive character, new girl on the scene is very nice but can argue in an empty room. I really do love my long term partner now ex, but I cant help but think I have done that much damage now that it has broken her and it will never feel normal despite what she says to reassure me. She has said some deep things in the heat of the moment about me and rightly so, but I am well aware she meant those things.
I already know, I am a piece of sh**. I am not looking for pitty or sympathy from anyone. But can anyone talk from experience here? Do I get back with long term ex and mother or my children and both of us live knowing what has happened, and that it is likely to come up from time to time. Or do I simply let her go and own my mistakes despite her wanting to get back.
I appreciate anyone who finds the time to reply to this. I am guilt ridden and leaving her for good would crush me. But it is my own damn fault.
