That sounds like a rough day. give yourself a bit of time on it then let it go (and rise like the break of dawn)
no 3 on your list I got on BD and its been consistent since so it absolutely feels like my W is 100% done with our M and maybe she is. Its really hurtful especially if they seem relaxed and happy about it.
Feelings change for good or bad and we have to make the best of whatever we are dealt.
Personally I think this is place for people who have a sense that if we work on ourselves things will work out better for us - whether that means a renewed and better M or something else. either way you need to live your life as best you can and be a great example to your D (which you are).
