instead of not being civil, he is actively making sure he keeps you at arm's length. You are, after all, in sort of a "trial separation", right?
It was supposed to be "trial" for four months but then we mutually agreed to extend it. In my mind, it's no longer "trial". I can't imagine he believes there's any hope for us either, his language has changed, it's now "my" house (not ours) and he references me as "name the kid"'s mom instead of W.
What would be the benefit of keeping me at arms length on purpose? Sincere question. I never bring up the R, or talk about a joint future. And he assumes I'm dating. Why distance me?
