Sometimes the right things are the hardest things to do...
However if it is in the best interest of your current realtionship, and you want to see that through, then the loss of a friendship could be the cost.
I remember that when I got married, my husband was uncomfortable with a couple of my guy friends. Admittedly, the lines of 'friendship only' had been (in the past) a little grey...
In the end, I let the relationships go, and almost 18 years later, I have NO regrets.
I don't know it this helps or not...just my experience and something to think about
maybe.
