I was a single girl about a couple of months ago and I came across a girl who is married but was looking for a girl friend. She asked me not once but twice on two different dating apps to come and be in their relationship as their girlfriend. Because I was looking for something new and bi curious, I decided to agree to this and we began to text regularly, the three of us but mostly her husband he was VERY open and excited about meeting me, he sent me numoerous videos ans photos of there relations and of his manhood. I kind of liked that and eventually I met them. Soon after I met her husband and her in person things were great and so much fun. At first I was into her to test my bicuriosity. We even moved in together. But recently I've fallen head over heels in love with him. And I feel like my heart is breaking and I don't know what to do. I'm so scared to end this but I just don't know what to do anymore. I'm either sad or distancing myself. I'm 20 years old, she's 20 and he's in his 50s.
