Cutting right to the chase: M1 is no more.
Although, I do not even know if I can rightly call it "breaking up." Whenever anybody asked me about this whole M1/M2 debacle, and asked if M1 and I were "going out" or "exclusive" or what-have-you, I could only reply that I did not exactly know. We had never had any discussion about it. I have not even seen M1 since before he went out of town last weekend, when having just such a conversation suddenly became important. But for simplicity: we just broke up.
I suppose it is what I deserve, after all, given the events of the last week. But, oh. I was looking forward to seeing him tonight.
Now if you will excuse me, I have to come up with some sort of reply to a break-up email.
