<human>: I dated this guy for almost a year.  He drove me crazy and was super controlling.  It took forever for me to end it because I was scared. He still thinks he is going to get me back.  Its been 5 months.  He knows I've seen other people in these months.  I still text him back when he texts me and we are still Facebook friends and I know this is bad.  I just felt that the dick video was really uncalled for and I don't know the right way of telling him that I don't want that kind of relationship with him and would really rather to hardly hear from or see him.  I think he might be a redditor and there is this part of me that hope he will see this and just know that this is about him and then it can be done with.

Summarize the given text in a few sentences.
<bot>: Ex sent me a video of his dick and I don't want that type of relationship with him. What do I do?
