Do you want to save your m?

If so you will not if you date. You need to decide if she is worth it. If so then stop dating and focus on yourself. I am sorry I don't know your whole story. Spend time with your son he needs you.

If she knows you are dating it will justify her reasons for her A. I can see the whole thing spiraling out of control and any chance of saving the m would be lost.

Please think long and hard about what you want. Read DR if you have not. You say you have not done anything against your wedding vows but you are dating and that does go against wedding vows.
