Tittles;
I have been watching the progress of this thread with great interest. It appears that the issue here isn't about love, trust, or what's in your heart. I think it's about honesty. I'm not talking about the honesty that you have for each other, although that is critically important, I am speaking of the hoensty within yourself. When one chooses to go down a path, they know either way whether it is a good idea or a bad one. Often, we as humans choose the bad idea because we trick ourselves into believing that it is the right thing to do. Don't let your mind play tricks on you.
Also, don't let your daughter influence your decision. by making the wrong choice, you are not only hurting yourself and your ex, you are hurting your daughter. Good luck, this is never an easy problem to solve. I hope I was of help.
