His crazy EX, help!

Mads • ~Mads

I met my fiancé 2 years ago, he's the love of my life and he says I'm his... I want to marry him, but we have already been through a lot. growing up I had some family issues that involved something I didn't want in my life, he broke that rule and I struggled for a long time... through all of this his ex has been around too making it all the harder. he kept a keepsake fox she made telling me it was just cool and that he would return it to the family because he didn't want to discrace it. it caused a lot of fights till finally it ended with him throwing it away. a half a year later school started and she joined his collage, showed up at our church, and joined his ROTC airforce group, even works on his base. I've had enough... there are no feeling there he says, but this vendetta is consuming me and I'm all alone... no friends or family. I feel hopless, depressed and completely lost. any advice on how to move on?
