<human>: I had been dating my ex for three and a half years, we lived in the same town and had similar friends. Aside from some issues in the begging things were fantastic for the majority of the relationship and I was planning on asking her to marry me in a few more years.

During the last year of our relationship she became more distant, took school way more seriously, and started hanging out with other people. It was a struggle for her to text once a day and we would see each other maybe once a month and generally not for a long period of time.

It has been about 6 months since we broke up. I still think about it every day, it causes me anxiety and puts me in a terrible mood. She on the other hand is relatively unaffected as I am fairly certain she had moved on at least 6 months before the relationship ended.

 This month we are going to my buddies cottage to which she was invited to before we broke up and is not being uninvited. She is friends with the people going but to a much lesser extent than I am for all except a couple people. I'm not sure how or if I can handle her coming to the cottage and how should I handle the situation in general?

Give me a shortened version of the text
<bot>: Can't get over ex-gf, she is coming on a cottage trip this month and I don't know what to do.
