Occasional poster, have name changed to avoid outing...
I am in my mid 40's and have been with DP for 3 years. DP is in his early 30s and we have been living together for the majority of the time we have been in a relationship.
We get on well, want similar things and we both love each other.
I recently found out that DP kissed a girl at his tennis club and followed her back to her house, where they continued the intimacy, but did not have sex. This happened over a year ago. For unknown reasons, he decided to not see her again after that night. He claims he stopped because he realised he loved me too much and could not bear to lose me.
I found out about said incident as I happened to be using his phone and messages from last year are still stored.
I am very confused. Please help.
