Sure it may be a less harsh blow than full on intercourse but trust has been broken and the relationship foundation has been cracked.
Do I think a relationship should end over a kiss? No.
However, I also think there is room to save a relationship after intercourse as well.
It all depends on the relationship, what it’s been through, what it was built on and what each partner can handle. If you’ve got one partner that has a mind that is relentless with thoughts of the indiscretion, constantly ruminating, it will be less likely to heal.
Research studies suggest that after an indiscretion, it takes 3-5 years to re-build trust.
Sometimes the indiscretion can bring the couple closer, while for others it will just bring closure.
If you want to heal after something like this then you are choosing to move forward. Your thoughts must also move forward and that starts with re-training your mind. When painful memories come up, you have to rephrase the way you think about it.
Keep reminding yourself you made the choice to move forward and keep the relationship or close up the books and move forward alone.
