Guh. I know how you feel. I’ve been there. Twice. Let me tell you, it is terrible to be in love with the wrong person. Really, terrible. The only thing that worked for me was to avoid all contact with that person. It is really really really hard to do at first. You’ll be depressed and upset and think you’re making the wrong decision. But. It gets better. You’ll soon realize that you don’t need her to lead a fulfilling life. And eventually, you’ll wonder how you could have ever felt that way about her.
