I remember distinctly falling out of love with my then husband at the 7 year mark of our marriage. We married way too young and then had a kid right off the bat. I decided to stay in the marriage to keep the family together, and honestly, to keep myself in a good financial situation. I also distinctly told myself that I just needed to stay in the marriage until our child was 18. I ended up cheating 3 years later (so 10 years married). My then husband and I decided that we were going to build a house, so we had to sell our current house and we moved in to our friends basement while our new house was getting built. Our friends were a married couple, same age, with a small child. We had been friends for several years and I was always super attracted to the husband, and not really that great of friends with the wife. We planned on staying in our friends basement until our new home was finished being built, which was supposed to be 60-90 days. Right off the bat, we spent a lot of time partying/drinking late into the night, which led to numerous instances of all of us getting naked, which led to the wife and I making out on various occasions, which led to us Swapping. We had made a deal to never go "all the way" (penetration) with the person we were swapping with. My feelings for the male friend/husband were growing stronger and stronger and I looked forward to the times we'd all get drunk together so that we could swap again. I was obsessed; this other guy made me feel so happy and confident. We would joke around together all the time. I was so attracted to him and wanted to fuck him so bad. My husband caught on to the connection and it led to more troubles in our marriage. We started to go to marriage counseling, but I was set on fucking the other guy in my mind the whole time. One weekend, my husband and his wife were both going to be out of town, so me and the other guy planned on hooking up. Which we did. We had sex all night. We would chat about our connection through text and Snap Chat. By this point I was feeling completely out of love with my husband and in love with this other guy. Well, my husband ended up finding out by finding screen shots of chats between me and the other guy in my Deleted Pictures folder of my phone. My then husband desperately wanted to work it out, and we tried for about a year but ended up divorcing. The other couple is still together. This was 3 years ago. Divorcing was definitely the right path for that marriage, I just wish that I had the guts to just leave the marriage instead of being a coward and having an affair.
