My life partner just told me she went out with a male friend of ours and had sex. I am devastated. We’ve been together for 5 years and I never thought this would happen. She said she just wanted to see what it was like with a man. I haven’t been able to sleep or eat for 3 days. Now what?
Whenever there is infidelity, regardless of sexual preference, it cuts us to the core. It doesn't make any difference whether it was with a male or a female. Your relationship has a deep, open wound. You need to work with a professional that can be objective and guide the two of you to establish what you both want your relationship to look like, including marriage. It will take time and lots of work to overcome. You will have to decide for yourself whether or not you want to do that.
