Is that hurtful or something I should just accept?
One thing that has worked real well for me is when I am in doubt is to simply take a couple of deep breadths and wait for the doubt to clear up. Wisdom will come if you are patient. Since you don't really know what is going on any decision you make would be based on guess work, emotions, worry and the behaviors of your previous partner. Doesn't sound like a strong foundation to be making big decisions on to me.
A good Buddhist saying is when in doubt do nothing.
