Love is a choice.
From what I understand, this happened about a year ago? What's been going on this entire year? Does his actions speak for his words? Have you done trust but verify? Have you done some investigation and does it reinforce his actions?
Sometimes during R, you have the feeling it's not over and it's your emotions getting the best of you - if you feel this way then look at the facts and look at it logically. How my fWH and I did is he would give me key words of comfort and enumerate what he's done recently and so far during R to be a better person. Honestly he continues to do this and doesn't mind doing this forever so long as he sees improvement that I am not harping on the past either. Since we're in true R, that helped us move forward for 5 years now.
Do I worry after 5 years? When you get to the point that you respect yourself again, have confidence again, etc. Even if A happens again, it doesn't matter anymore. I know what to do. In my case, I know to leave and never look back with my head up high that I tried my damndest for my marriage.
Now I ask you, do all the facts add up that you are in true R with him per his actions? If the answer is no...
Hugs your way.
True love is harder to come by than soul mates. True love requires work.
Ignorance can be cured with knowledge. There is no cure for being an idiot.
