Well, yes, that could be a reason. People who cheat, or who plan to cheat, have a character flaw and are not honest. When things move very quickly, yes, it's easy to miss such flaws because you're caught up in the initial whirlwind romance.

So, perhaps next time you slow it down and get to know the person better before committing your heart or parts of your life to them. Perhaps that's the lesson to be learned here.

Plus, you probably didn't initially know that she would want to stay chained to the house all the time. Given your posts, I wonder if she has depression or some sort of mental health issue going on. It seems it since she is so tired all the time and wants to stay home.

I am very sorry you got so hurt. No one deserves to be cheated on, even if it hadn't happened yet, it was still the plan and she was sexting. I know how awful it feels. I've been cheated on several times over. She is not worthy of your heart. That's how I always look at it. Next time, you will be sure to find someone who is honest and faithful. That's what you need to carry forward with you.
