I'll try and make this as short as I can, I work with a woman who was in a abusive marriage, he hit her , was abusive and controlling, 8 years ago we started to flirt and get close and I started seeing her, we would meet up when it was possible and we fell in love with each other, it was hard to meet up but the time we had together was fantastic, she kept on saying she was leaving but he always manipulated her to stay, she'd been with him since she was 14 and now she's 49, so all this has been going on for the last 8 years, in January of this year she did leave him and I was the happiest man alive and things were fantastic, then in July she said she wants some space and wanted to sleep with other men and see what's out there because she has never had the chance to do it, I was devastated and begged and pleaded her not to do this, so I gave her some space and I rang her 3 weeks later to tell her how much I missed her, in that 3 weeks she told me she had slept with 6 other men and that she is loving it and doesn't want to stop sleeping around but she said she misses me and still loves me but she has got to do this, she is very stunning and she said she is even sleeping with men 20 years younger than her and she is loving the attention,I love and miss this woman so much, I'm so depressed and I just don't know what to do.

Forget her, since one she left a relationship that you were cheating with her on. Not a good way to start. She now has freedom and wants to try it.

Or you can be with her and be in a open relationship allowing her to sleep with other men, and then come home to you.

Really only two choices at this point.

Geez guy, what would you expect from having an affair with a married woman. She has her freedom and wants to keep it, and explore it.

Let her and leave her alone now. She need a LONG healing process now.

Sorry you gave your heart to someone that didn't know what to do with it, so start your own healing.
