Hey mate…

Easier said than done, but from an onlooker with past experience with heartbreak…
You and I both know that you cannot simply be friends with your ex.
You still love her, and will feel that way for a while. A year is a long time to do a lot of things together, and you feel like it would be a waste to let it all go now.

She’s made it clear that she sees nothing long term with you.
I know that hurts, but you’d be a fool to try and talk her into it.

I still have issues with letting go of my past (Was in a 3 year relationship with someone and broke up last July).
I’d probably have saved myself a bunch of pain if I didn’t let the relationship go on as long as it did.
We broke up and got back together so many times.
Habits are hard to break. And nobody really likes the unknown. Unless they’re some adrenaline junkie with no fear.

But, you already know what you need to do.
Delete her number and do everything to avoid making contact with her. That scares the heck out of you, doesn’t it?
If you really feel the need, give her a ‘Take it or leave it’ option, but again – That’d be foolish, as she would stay with you if that’s what she wanted. But she doesn’t…

Keep the fond memories of the relationship, but realise that it ends here. Things would go back and forth for a long time. Why? Maybe you’re just not right for each other. Maybe she wants to have more fun before getting into a serious life commitment. Maybe you weren’t a great partner – I don’t know! You likely do though.
You’ll hurt for some time, but that’s life. Sometimes it makes you wish you were never born.
In time, you’ll regain strength and become a better man.

Hope this helps. I didn’t want to sugarcoat the truth.
