The thing is NONE of us know what will happen tomorrow or the day after that or next year or a decade from now. So "feeling" that your H will come back to you is pretty senseless. IMO you have convinced yourself of this and that is why you are having such a hard time.
Have you considered seeing another therapist? I ask because your current therapist doesn't seem to be teaching you how to create goals or find solutions. Telling you to hang on for one more week is helpful how? IMO that keeps you in another week of hell. It is unfortunate your H brought his mistress to the game but in all honestly it is a public place. Your H has proven time and time again to be beyond thoughtless so this should not still be surprising to you, right?
If your H opts to stay with this "lady" then you will have to see her from time to time as you and your H share a son. Are you going to allow this disgusting home wrecker to throw you in a tailspin each time?
How can ONE person be your life? C'mon now! I have heard you mention your sister and mom. You have a child. There is now way to live a healthy live thinking ONE person can be your life.
Now look, this sucks to high heaven and I would like to kick your H right in the balls while wearing my highest heels but that won't help you.
You must learn to help yourself. You have an awfully big cheering section right on this forum.
