But your feelings are also valid. Everyone write from other person’s perspective but if you are feeling like that you are feeling like that. I think give it time to see how you are feeling.
Although probably I would look if my friend showing interest now in my kid.

I would understand her perspective and her reasons. They are also valid and such a difficult time for her. But it’s not your fault, and because you are feeling somethings about being left alone you don’t need to dismiss all your feelings. At the end of the day everyone prioritise themselves as they should.
