Well, my no contact attempts for the day:

SO called around 7 for D7; we didn't speak
Called again around 8, I answered. Reiterated what I told him about no more. Told him I had to go out; also told him I was still trying to find a job
He called again around 12 - I wasn't home. His message said "how come you won't talk to me or pick up the phone when I call" About an hour later (when I figured he'd be sleeping I texted him with - Sorry - just got your message. Was out.
He called around 5, I let the girls speak with him, then hung the phone up.
He immediately called back, I cut it short. He asked if I had emailed him/texted him - I asked What for? He said he was just wondering.
He called again around 7, this time I heard him saying he wanted to talk with me, but I hung up. He called back - questioning why I wouldn't talk with him and that he always wants to talk to me as well as the girls and he wanted to tell me to have a good nite. I said OK, thank you . You have a good nite, too. He said "OK, I'll call you later." ????
Just now, I was online trying to type this and he signed on from his laptop and tried to IM me. I didn't answer and got a sarcastic " well, whatever, thanks for ignoring me". Honestly, I just found this annoying. I'm not even going to waste a thought on it.

So, I didn't once contact him today, but received how many calls? Texts? Emails. I'll leave it up to you all to count! And this was a quiet day!!

How do I nicely (Or not so nicely!!) tell him to stop this? I'm not sure it's good for any of us. Once again - he ended it with me. Is this the behavior of someone that is supposed to be my ex? Someone who has OW? When I point this out to him, his answer is "I know"!! It's all so very confusing.

I also finally worked up the courage to email both his mother and his father & stepmother. They had been emailing me & asking questions (they usually speak with me more than him normally, lol) and I had been avoiding them. I sent a simple email that said:
"Thanks for your words. Not sure if you know or not, but SO has gotten his own apartment and moved out 2 weeks ago. I don't really have anything else to say about it right now.

For the time being, I plan on staying here. I don't want to uproot the kids, especially D7 in the middle of a school year. I'm looking for a job, probably something part-time because I won't put the little ones in daycare full-time. That's what I'm working on at the moment.

As for the future, who knows. I will not be pressured or forced into anything I'm not comfortable with. I plan on taking things one step at a time, hopefully things will get sorted out, whatever THAT means. "

So far, I've only heard back from his Stepmom/Dad who said they knew he moved out and that SO isn't "overly excited about talking to us because he knows how we feel about his behavior."

I almost feel bad for him. I don't want to defend him, yet on the other hand, with the DBing that I've learned, I know that if they (parents, family, friends, etc) give him a hard time and "gang up" against him, that may not be for the best either. Don't know what, if anything I should do there. While it is HIS family, I'm more in touch/contact with them than he is and it's been that way for most of our time together. I wish I weren't involved! LOL
