Friend Criticizes Me About My Broken Engagement, after he proposes to a girl he met

[GuitarMan13]

4 months ago.? My fiancee, whom I dated 4 years left me in June of last year, stating that she needed to find herself.We had and amazing relationship and I loved her more than anything Needless to say I was completely devastated from this happening. My best friend of 14 years joined EHarmony during in October, and met a girl. He proposed to her 4 weeks ago and has already signed a lease on a condominium. He constantly tells me how great there relationship is, and obnoxiously to give me pointers on what I did wrong with my ex. I have confronted him about this on numerous occasions, but he continously tells me what he thinks I have done wrong. I NEED ADVICE!! How do I tell him to stay out of my business, a relationship that he knows little about? The breakup was hard enough for me, and I don't need criticism
