Is this the end of my love story?

A Story by Tony

A Painful Test of Love.

I met "C" through instagram almost 5 years ago. He started following me after he became friends with one of my friends. We barely communicated except for that day I invited him to join our group in attending a weekend music festival here in Chicago. He hung out with me and my friends with no intentions or pressure of anything else otger than friends.
On the 3rd night of the festival, magic happened. It was literally like stars aligned and Cupid shot his arrow to my heart. This sounds so cheesy but I'm telling this story as easy as possible for someone to understand. I looked at him and he had tears in his eyes. I grabbed his hand and the connection instantly happened.
We were inseparable since then and decided that he moved in with me 6 mos later. . We did so much together and named each other soulmates. I have never met anyone who I deeply cared for, had deep connections, and loved more than myself. I gave him my all and I believe gave me his. We had something very unique and special. Whether we travelled or just chilling on the couch, there was never a dull moment since we knew we were together.
On October of last year, after over 3 years of love, fun, trust, trials, and understading, I proposed to him in a very special setting in front of our closest friends and his mom. He said yes.

Two weeks ago, I went with my roommate to Montreal for a weekend get away. "C" wasn't able to go since he had to work. Trust has never been an issue nor we were never worried about temptations or anything.
Since we came back, we've barely seen each other. I've been working hard and putting in long hours at work. I work early and he works late. I'm in bed by the time he got home and he's asleep when I leave for work. Nevertheless, we've never missed a day without a kiss and tell each other I love you, whether it's via text or else.
Fast forward to last night. I decided to do something special and surprise him when he got home. I cleaned the crap out of our living room and rearranged the furniture to set up our camping tent. I prepared snacks, did a champagne set up, got the airbed and decorated inside and out of the tent with some lights and all.
When he arrived through the backdoor, I greeted him with a hug and a kiss and asked him to go shower toe buy me sometime so I could complete the romantic surprise. We haven't spent quality time in a couple of weeks so it was going to be another special night. As he entered the living room and started to see what I've done, he gave me a hug and began to cry. I asked him what was wrong and he couldn't reply. What I thought was tears of joy became something I had never thought would ever happen in our relationship. I asked him if he slept with someone and he answered yes. I took a deep breath and continued to ask questions. He said that it happened while my roommate and I went to Canada. He proceeded to tell me that he met the guy through instagram also. I felt a deep stab in my heart when I heard him say that. It crushed our introduction story.
Between the piercing silence and the soundful tears, he continued to express his regret explained that it was stupid, meaningless, and that it was a mistake that would never cross his mind ever again. He said that at that time, he somehow thought about our engagement and chose a bad decision of getting that curiousity of being with another man out by doing so before the official marriage. He said he couldn't bare in his mind to keep it as a secret and that he had to tell me.
As confused, angry, and heartbroken as I was, I had to keep an open mind and gather myself to avoid making any rash decisions I may regret.
As of standing, I'm here writing this long heartbreak story as a means of release. It may not solve anything but rather help me collect my thoughts and share it somewhere rather than keeping it inside me. I would rather not tell any of our friends or family as it too will break their hearts.
I still don't know where we to go from here as I feel empty. I feel a familiar pain I've felt before but this time it really hurts. How do one rebuild trust if I decide to move pass this. How do I look at him and not feel angry? How do I erase the imagination of his infidelity with that other person?
I love him and will always do. Damage is done, I don't know how to go on. I'm broken. This really sucks!
