My beautiful boyfriend of 5 years has recently broken up with me, but we still live together. He's moving overseas indefinitely in 4 months time. 

He's looking for a room to move out and I find that I'm doing everything I can to convince him to stay with me for the next 4 months - I can't help but desperately cling onto him. Today I found a message he sent to a girl asking about a free room in her sharehouse, but she was super attractive and single. I have kept my cool but man did I cry and cry and cry in  my sleep last night, I don't think it's fair.

What are your tips for setting boundaries or ignoring your ex-SO when they want nothing to do with you?
