<human>: Can you condense the text into three sentences or less?

So I dated my ex for three years.  We were best friends before we started dating and broke up on mutual and good terms (because we knew that marriage wasn't in the cards for is due to different life and family goals).  We were broken up for a year and still in contact when I met my current bf.    

My ex was very distraught when he learned I had a bf and we stopped communication after an argument.  It's been almost two years and we haven't spoken.  I am still with my current bf.  

My ex is best friends with my best friend, and will occasionally keep in touch with members of my family (because he was close with them and his family situation is often tense and unsUpportive).  He lives in a different city (same city as my best friend).  My ex has had a new gf for about four months and I would like to smooth things over with him to bring a more peaceful resolution to the situation.  

My current bf argues that he doesn't see the point and finds it ridiculous that we would even be discussing my ex after two years of a relationship (he is also sensitive because I reached out to say happy birthday on facebook to my ex after we stopped talking in an effort to remain friendly at least, my current bf was very upset by this).  

My bf says that I need to let it go, but for some reason I feel like I have to hold up this grudge that just adds tension and stress.  I would like to resolve things.  

Not sure how to navigate the situation?  Was hoping someone would have some insight or similar experiences?
<bot>: Would like to be on peaceful and friendly terms with ex after two years of not talking as we share similar social circles.  Bf is angered by this.
