All i can say is.. she's not worth puzzling over.
I don't understand how she could agree to marry you when she's going out with someone already..
I think her mothers death has messed her up a bit and she's not ready for any kind of relationship
Try being her friend and friend only.
It sounds like thats what she needs right now.

Yeah i quess i am

Maybe you need to stop being sad and get angry at her, she did something really horrible to you and it's no excuse even if your mum is dying, really it's more of a reason to not be devious and lie. you proposed to her, and she expected for you to never find out she had TWO partners? she doesn't sound like a nice person, and was probably using her mums death as an excuse to get you back.

You only found out an hour ago right? Well you're not going to get over her in that small amount of time. She's definately not worth your love give it time and go out and find the one who deserves you.

Geez. I think this girl has problems.

Ok now i know its reallly hard(espically after only an hour) but i agree with the other people in this post. You need to find someone else. I dont blame everything i guess that this girl did on herself because obviously her moms death hurt her badly but still..anyone that agreed to marry you but still had a bf...that wouldnt work out...
