I am curious as to why you admitted to your 'Girlfriend' that you cheated. Either you felt guilty and wanted to unload your guilt, or you felt that to move forward in the relationship you felt that she should be informed? Either way, there is now underlying distrust between you both.

Relationships in my opinion aren't designed to 'imprison' each other, but to move forward with shared goals and support each other in personal endeavours. Now that the proverbial 'cat' is out of the bag with regard to your indiscretion, you need to both agree to move past your mistakes, or make the choice to part ways.

It's all well and good to be on the same highway in a Relationship...but it works best when we are in different lanes in my opinion....There has to be a degree of autonomy.
