"how do I fix are relationship and dix his broken heart and get him feel the love again?"
Among many things, the one who is being cheated suffers a blow to his/her self-esteem (what's wrong with me?)
You can help him by telling him that you found, and read this. This may ease his self-doubt a bit. You are also showing him that you are serious in wanting to restore your relationship.
"A person who cheats has unexpressed feelings and unmet needs inside them, as we all do. However, too afraid to speak their truth and express their feelings, they take out their frustration using other people as their outlet...Our society has a general unwillingness to face those parts of ourselves that are uncomfortable to deal with."
This tells him, "It is not your problem."
Tell him you have decided to work on yourself, to get to the bottom of whole issue --- tackling it at a root level, so that the chance of your doing it again is eliminated, at root level. This, hopefully, will release his biggest doubt, "Will she do it again?"
If you (and him) are up to it, you can work the questions below together. I don't see any reason why not. Yes, this is a major operation, on yourself. It can be painful. The way I see it is ---- if you can go through this, you will have his respect back, at least. It is a good start. How can you love someone you don't respect?
As to the ultimate goal, saving the relationship, it depends how thorough you work these question, and his response to your efforts.
Whatever happens, you know you tried, seriously, to mend the relationship. Best of luck!
The questions are :
Why do you cheat? What unresolved issues or unexpressed emotions are trying to get your attention? What positive feelings do you get out of the experience? What negative feelings come up? These will give you clues as to your deeper wounds – there is something your inner child wants, eg acceptance or validation, and there is something your inner child wants to forget, eg shame or neglect. Find out what your inner child needs, and what she most wants to heal. Be there for her now.
What do you most need from yourself, your partner, and life that you feel you aren’t receiving? How can you get your needs met in healthy, positive ways?
Are there other addictions in your life? Work with an appropriate therapist to help you uncover the root of any addiction issues.
Start journalling. This is an extremely powerful and safe way to uncover your feelings.
Forgive yourself for not being perfect – no-one is. When we learn from our mistakes we give them a constructive purpose. This is a key step toward feeling worthy enough to attract a healthy relationship into your life, or heal your existing one.
