Thanks for writing in for help with your relationship. Whether or not she breaks up with you, it’s important for you to get to the bottom of you why you continue to do things, like lie and cheat, that you know aren’t a good idea. Frequently, relationship sabotage has roots in past hurts. Is there anything in your relationship or family history that might be emotionally driving your pattern of pushing your girlfriend away? Your emotional detachment to her sadness also suggests that there may be something that is unresolved for you in close relationships. I suggest that you get a therapist and explore what’s driving this pattern so if your girlfriend stays with you, you can learn how to maintain closeness and if she breaks up with you, you can prevent this pattern in future relationships. Also, consider reading the book “Getting the Love You Want: A Guide For Couples” by Dr. Harville Hendrix to help you start understanding the deeper patterns that may be getting in the way of your love relationship.
Take good care of yourself and your relationships!
