Maxxadict,
You speak words straight out of the mouth of my wife. In fact, I would think you were quoting her if I did not know better. Our situations are completely inverse… and my heart goes out to you. I have the same questions as you, but am asking really for my wife, as I seem to being doing far better with this than she is.
After years of ABC I decided I could no longer live that life and approach the alter of my Lord with this sin in my heart. My wife (cradle-Catholic like me) was devastated, and remains devastated. She hates NFP (sympto-thermo + monitor) and becomes very irritable and angry every month during the abstinence phase. Discussing any matters of why this is important to our faith or how this could help our marriage is useless. She fights it tooth and nail. She is angry with me, refuses to speak with me. Meanwhile, I go to mass daily, pray, fast, attempt to approach her with love, but get anger as a response. So I know how it feels from the other side of the fence (not good, let me tell you, brother).
Things have not gotten better after 7 months although the NFP part of it works fine, is predictable and manageable, as far as I am concerned (I help chart, get the thermometer at 5a.m., etc. - a lot of good that does me…)
While it was never my intention to “ruin” our marriage, this is the accusation thrown at me every month. I am accused of not understanding, if I even hint at the idea of “virtue” as others have mentioned here, - off with my head. I will read Fr. Groschel’s book on virtue, because I really need more virtue myself. I love her, will not leave her and will be patient with her, and my heart aches with sorrow for her frustration and pain. Ouch. Experienced NFP couples, pray for me and Maxxadict and others like us, and offer help and advice if you can. Mater Dei, ora pro nobis.
