elvira, so sorry you are in pain. such a difficult situation you have written about. I know somebody going through this same thing. she decided it was best to let go also. there are some wonderful SINGLE men out there. keep the faith!
You know Elvira, On the other side of the coin, it's extremely hard when there are reasons (I know it's not right), but if you're happy, then let it be, if it makes you miserable, then end it...pretty simple, but not really!!!
