Hey Nicole, as I said on other thread, IMO you are doing really well with the boundaries.
The KISS- Ok, he touched YOUR body and then you kissed him and then you felt rejected and apologized. Maybe homeboy needs to keep his fingers to himself and it wont be so confusing. 25 would know better if you should let him go there but I think it was a bit of ok for him to do it, but not for you...and, now you know.
You aren't going to get through this with 100% stoicism. On the main issues, you held your ground. Stick with it.
H asking you about if he could feed the kids chili cheese fries is a clue into your R. Why would he need to ask you that? He doesn't seem to know that he is in charge when he is with them or feel capable. That could be something he needs to glean from this sitch, that he has to be a man and father and make those and MANY decisions, especially if he wants to be on his own. Again, just my opinion. But, I have gone through that with H and had to really back off and let his time be his time and sometimes even saying, "that is your call." Hopefully, 25 can expound on this topic as I feel a bit self-conscious...I don't want to project, that just really stood out to me.
Again, nice that he is not blaming you and willing to admit this is his crisis. That puts you in a much more honest and manageable space (I think).
As for his agenda, none of us can say. BUT, it does seem to me that you doing what you need to do for you is working and that you should stick with that. It is what has taken me 4 months to make peace with and I have no regrets but you can do it now.
