<human>: Give me a shortened version of the text

Been dating a friend casually for the past 3 months, from an early stage I made it clear it was meant to be casual predominantly as I had exams coming up. Some days before my exams, he asked me to marry him. I laughed it off as we had always kept everything as a joke. Then the day before them, he told me he was off back home to marry another girl he'd been seeing with the intention of marriage for much longer than he'd known me.

He came back recently, wanting to continue our casual relationship inspite of his engagement. To add to his character, I recently found him to be engaging in illicit activities I won't go into detail on but that completely shocked me. 

Odd how our personalities were almost identical but our realities are completely contrasting. 

In summary, this event didn't make me feel a whole loot good about myself and my disillusioned view of relationships, or at least those I will be in continues to be ever cynical. 

Perspectives?
<bot>: Broke up with a law-breaking ex because he got engaged to someone else after I refused. No longer care for him but left with a disillusioned view of relationships in the future. Perspective?
