1. You move on with your life. Continue to grow as a Man. Have firm boundaries in place as you navigate through co-parenting ,being a father , new relationships and live your life to the fullest.
2. She comes over says. I made a mistake. You go. Yay! She takes you back right away and change in what ever ways you think will make her happy. Down the road when she is not happy anymore again she knows she can cheat or dangle it at you for awhile and the only consequence is you will do anything to make her life better.
3. You two get back together and do not grow as a couple and learn how to communicate and have strong boundaries in place for the marriage. Separate in a few years.
4. She peruses you and you two get back together. You have strong boundaries in place so the next time she does this you D her and end the relationship forever. Just co-parenting and that is it.
5. She pursues you and you both work out what you want in the relationship. You both work hard to improve your selves. You have a strong relationship that is based on communication, trust, desire, friendship, compassion and equality. You both have strong boundaries that you both understand. Your marriage has strong boundaries. When issues arise you find solutions and implement them.
6. You move on. Do not grow as a man. Get in a new relationship, repeat the problems again and that one ends....
What I am basically saying to you is that there is only one thing that you can control in life.
YOU.
If she ends up with a nice guy. Then good for her. If she ends up with Mr. Douche-bag. Then good for her.
The only thing you need to worry about is you and your son. If she is not fit to be a mother then you go for full custody.
If she is fit to be a mother then you co-parent and be civil with each other and do what is right for the son , work through issues and do not take advantage of each other. Civil and considerate.
You control only you.
Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul. unconditional love is awesome!
