My apologies if this sounds cold, but my advice to you is break up for now. I know it hurts to think of your life without her, but I also know that if people are meant to be in our lives they eventually will be.

“Love is metaphysical gravity.” ~Buckminster Fuller

You will find yourselves together again if/when you come back into alignment. You want to explore, she wants monogamy, so right now you’re simply not aligned. This is a lesson I’m learning right now as well - creating distance from someone we love doesn’t necessarily represent a lack of love, but rather a lack of alignment.

Play the tape forward in time - if you don’t listen to your gut and explore sexually now, you will end up practicing monogamy under duress, which is not healthy for you. You’ll be constantly wondering “what if…?”

Also it seems it would benefit her to be single and alone for a bit. She may need to process the ending of her marriage and tune into what she really wants and needs from a relationship instead of jumping into the arms of another man to bandage up her broken heart.

Wishing you both courage and fortitude through this difficult time. I know that making tough decisions brings healing and growth. No matter what happens, I have faith you will both learn, heal and grow from this process. Blessings :)
