Should I stay or should I go?

I would remove this ex from any part of my life. He is only prevented you from being happy. He is playing his new girl and you. How sad. As for the new guy I personally think you could fall madly in love with him if you could only remove the ex COMPLETETLY. I know it is hard because I have been there. Please remove the ex from your life even if you decide not to stay with the new man. This is only going to hender any and all relationship in the future if you allow this to continue. He isn't a good person and I hope you see this sooner then later. Take care.
