I agree with MrBond. Just like a spouse in an A, you are seeing the world through magical glasses because you are now in limerence. Feel good chemicals are being released in your brain, causing you to crave more. This craving is so strong it will easily overcloud all logic.
I'm not saying you are doing anything wrong or making a mistake.
Just understand that this stage you are in typically lasts 6-24 months. Ultimately, there is no way to know if this R will be any better than one with your W until you get through this period and see what you two have on the other side.
Meeting someone and connecting like you and new women have is actually one of my fears. I want to continue to stand for my M, because I know my W is worth it, and I know how difficult a dream girl would make it to continue to stay on track.
Enjoy each day and take care, my friend.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
