Won't stand for a broken family

[Timetotry]

Been awhile but I need to vent so bad right now.

Pretty much the same the last two weeks, he comes around, everything seems 'smooth and paved' but no committment or R talk.
Even can go as far as we are able to joke and laugh about some things, in my mind, progress. Thinking about the idea of 'tough love' no contact so there is no 'cake eating' but not ready for myself to do that just yet even though I said it 2 weeks ago. He somehow makes excuses to find a way over and says its for the kids.

He emailed this morning asking about D1 birthday dinner tomorrow so we can finalize plans and he made reservations. He asked about the weekend and even said "are we all going to the fireworks?". WE. I was feeling good and he asked me to call. So I did and we had a good convo for 5 minutes and again a few laughs. Had alot more "we" lately.

Tonight I don't know what to think. He called at dinner and D3 talked a few minutes then said how she went to the ortho to fix her hyrax. He said why? She said what I whispered at that time (since it was on speaker)cause mommy said you didn't turn it enough so they had to fix it. He responds "And there is the whole reason why the relationship fell apart in a nutshell. Its all my fault, not Mommy's". I laughed and said "I was only kidding, stop!". He said "No, I will not stop, you don't accept blame ever". I said "Its not yours or my fault, it was the nurse when she was testing it she didn't finish the turn and that's why we both had an issue". He said "D3 I called to talk to you, that's it, take me off of speaker". I then said "Hey fireworks are Friday, not Thursday". H said " Oh, ok that was strange but that makes better sense now". Then D3 finished saying goodbye.

An hour later I text him: "Not sure if you were serious or not earlier and want to apologize if you really were upset. The girl showing me last week didn't turn it all the way and that's why both of us had a hard time turning. Sorry, I didn't mean to get you mad if you were serious, it really wasn't your fault at all".

Never heard from him.

I don't know how to act tomorrow. "As if" or "distant". I can't not go, its D1 birthday.

I also don't know that if something that little is going to effect him in this way if its really worth saving. Its not fair to me. IC says to me again and again, everytime he points something like this out, its not my fault but his personality issue is to bring me down to better himself. I said I wasn't serious and even apologized again. What more can I do? If H refuses to accept that, then its really not worth saving I guess, especially over something as litle as this when he was caught (only admitted so far) to a EA.

So frustrated right now.
