how do you get over a friend that you are so in love with

They are still together? Since it is a friend of yours, I would suggest that you just keep it to yourself and look elsewhere for love. There are a zillion guys out there. You really don't want your friend's man. It would no doubt ruin the friendship. If you care about your friendship with the girl, I'd just back off from that idea. Sounds as if you have a huge crush. maybe you should give yourself some space from these two and look to meet other people. From what you said, this one seems off limits.

I think it is time to move on to a new relationship. There is nothing like a new love to make you forget an old one. Gettign interested in someone else will really help you move on from this relationship. It is something you need to do at this point. I wish you luck with this.
