Good for you for staying strong! I'm so proud of you!
So that was round one and sounds like it was pretty calm. When my ex abf started the "don't leave me" dance, as I like to call it, it was pretty tame at first. But it usually gets worse before it gets better... be prepared. The more they see their efforts aren't working, the more desperate they become. I had to remind myself that every time I thought about answering that phone/opening that email/reading that text message was another opportunity for him to get back inside my head. And boy was he good at it.
Keep your head up and yours eyes open, you're doing great!
