"I'm gonna come out and say it as all to often I beat around the bush - I'm still very much in love with you. I know this is something I have to own and live with but I hope you understand I had to tell you that. The truth is I've always loved you, I've tried so hard to move on, I thought if I could meet someone else it would take the pressure off our relationship, people would stop asking them damn awkward questions but in truth I never wanted to go and meet other women, all I was doing was trying to replace you but deep down I didn't want to replace you - I wanted you.
The reason I'm telling you how I feel is because I don't want to live to regret not telling you. You know the question we all ask 'What if'. What if I didn't tell you how I feel? I guess I'd have to learn how to deal with how I feel but along time has gone past without you and I still feel like I do.
I'm sorry I've brought this up, I've tried to think how it would effect how we are with one another after writing it but only the future can tell us that! I really hope you understand why I had to tell you - these feelings for you have literally consumed my life over the past weeks and months where it has been driving me crazy."
The above is 100% about what you feel and what you want. She doesn't care what you feel or want. You have to show her that YOU care about what SHE feels and wants.
