I Dont Want It To Happen Again.

When i was 18 i was engaged to a guy that i thought i would grow old with and live happily ever after. What i didn't see coming was him leaving me 1 month before the wedding. He broke my heart and it took me what seemed like forever to heal. Fast forward 4 years and i met a guy that is everything i ever wanted. we clicked almost instantly. we weren't together 3 months and i moved in with him. We decided he would go back to driving truck over the road and our dog and i would come with him. Life was great for 3 or so months, then we came home for a weekend off the road and the morning after we got home he broke up with me. Leaving me with no option but to beg my parents to let me move home. After almost 1 year we got back together and 7 months later he proposed. Now here we are little less then 3 months from the wedding and im starting to fear it will happen to me again. that ill come home and all my stuff will be packed or he will tell me one day that its not going to work between us.
