Feeling heartbroken

So I have decided to cut all ties with my guy friend who has been a great support to me this year during some of my toughest times. In choosing to do this I am also choosing to give up a part of myself that I've kind of just accepted. This is all very hard for me to do but I have to. I've started to develop feelings for this person outside of my marriage and because my spouse did not agree to be in an open marriage I will honor him. I can't help but to cry and feel heartbroken because though I truly do love my husband this person has been here for me and cared for me and offered great emotional support and has been a great friend to me. He's the only person that I have as a friend outside of my husband and my kids. I'm so alone and lonely here. I guess all there left to do is continue to try to work on things with my husband and see what happens and try not think of this as losing a part of myself but maybe just moving on from whatever. I don't even know. I should be grateful for what I have and not thinking about what u don't have.

You have made a very honourable and noble decision. May the future pay it forward in rich rewards for your choice
