You're right I do know him best. And I think he only said that his weekend was busy so that I wouldn't understand why he wasn't hanging out.
When we were in a "touchy" phase of me pursuing, he used to say I'm busy on Wed and then clarify with I'm helping my mom do this or I told friend I'd do this. If it was something with her, he'd say Sadly I have other commitments. So I don't think he's taunting me I think he was just trying to set expectations. At some point when he clarified to me it wasn't GF, I texted back that's cool you don't have to give me details of your plans.

I know exactly what you mean. I feel like I may have subconsciously done that when I was a WAW. I don't like who I was during that period.

The more I think about this shift....I think it's the DB kicking in. I haven't pursued. I haven't initiated conversations. And he's feeling that I've let go not just in name only. I may have told him last week that my feeling haven't changed, but I haven't attacked, reacted, demanded answers in over a month and I haven't flirted in almost 2 weeks. It threw him for a loop that I was involved in the medical drama and he knew nothing and I was just soldiering on. I think he's feeling a little unsettled in how much I want him in my life...and you know what I think that's swell!!!!

Let him continue to ask me instead of assuming that he's doing me and S a favour by dropping by!

I reread my text and it was exactly what I would have sent any friend..with the addition of hope your weekend is fun busy and not stress busy. But I can't do that in DB.
