<human>: Summarize the given text in a few sentences.

She and I dated for a while. Her ex-boyfriend was out of the country for two years and when he returned abruptly, she decided to get back together with him (secretly). She tried to break things off with me, though I knew the real reasons, by saying "I'm just not ready for a relationship right now". 

I recently spoke with her (via text) where she told me "I'm in a relationship now and I'm happy....I'll probably be getting married in the next few months". It really hurt to hear that, because for a long time, she and I had considered marriage. But she dumped me right when he got back to the states.

This whole situation has been very discouraging to me because she and I were really close. I loved her a lot, and I thought she loved me too. Now, I am scared and too discouraged to try getting into another relationship - for fear of getting close and bringing those kinds of affectionate feelings back, only to have them torn away again.
<bot>: Ugly break-up left me feeling discouraged, inadequate, and scared. I need help. What can I do to get over her and move on?
