Challenging relationship from the beginning. We met online through a dating website and live in different states but same time zones.

It was love at first sight. We fell hard, heavy, and very fast. Met in May, he came to visit me in June, I went to visit him in August, September he wanted to marry me, October we made plans to meet his family whom he had already told that I was the one he planned to marry. We were going to live in the same state soon.
s
2-3 weeks before our planned trip on October, I could tell he was distant, felt he was not as loving to me as he used to. I was worried and asked him to talk to me...he said he still loved me just said he was tired and busy.

1 week before the trip he breaks up with me and says he is unhappy and does not want to do this anymore, that it is too hard and that we both need to work on ourselves alone.

I tried so hard to understand what went wrong,... how he could love me and want me to be his wife and then cut me off. We had 2 minor arguments but talked thru them. I feel like it was me, I was not sensitive enough, i hurt his feelings, but not on purpose. He held it in and didn't talk to me.
If he would have said "Hey, you hurt my feelings. don't do that" then i would have said, "you're right, im so sorry, i love you so much". I just feel side swiped and was not given an opportunity to make the situation right.

I'm not perfect, I'm human. I was good to him. Honest, loving, transparent, open.

But then I feel like he threw in the towel over something small. Relationships take work and how couples work through them makes them stronger. I feel like he just wanted the honeymoon phase and once stuff got real he bailed. WHY would be even propose to me?? I feel coned, like it was all a big joke on me. Like he chased after me, and once he knew he had my heart completley he tossed it away.

He is still going on the trip to see his family. I bought my plane tickets, but he does not want me there. He said he told his family he would be going alone and that i could not make it. It was like daggers to my heart.

I feel so hurt and soooo stupid. Like I should have guarded my heart better, should have been more cautious. Not so careless. It was like a dream, and I just woke up. I wonder if he really love me or not.

October 19th would have been our 6 month anniversary.

We talked about building a life together.

He broke up with me saying that we are both damaged from our previous relationships. I'm just so sad because I truely fell inlove with him. I need to let go. But my wounds are very raw right now.
