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

So this past year a lot has happened to my sister (28). She was proposed to at the end of April with her boyfriend for 4 years. In less than 1 month, he broke it off. His reason was that he proposed to find out if he truly loved her. She started to go to therapy, subscribed to eHarmony, and was really upset for a good time. The relationship was not really the best. He valued money over everything else, he always listened to his mom, and took a job without telling my sister that he had an interview (this was probably where it started going wrong).

She started dating once again end September/beginning of October. Those dates did not go so well. She started dating someone within her field and things were going great. The only issue it seemed was their religions (he's orthodox Jewish, she is not). She was considering to convert for him if things worked out.

He took her to NYC to see broadway for Christmas and her birthday (last week). Everything went quite well and she told me that she was the happiest she has been in years. Well, after a few short months, he decided that he will marry a traditional Jewish woman and broke up with last night.

I need to know how I can help her to be happier. We live within minutes of each other right now but I will be leaving in a few months since I will be graduating in a few months.
<bot>: My sister has had an emotional rollercoaster (fiance broke it off, bad break up last night) this past year. How can I make her happier?
