I think I have feelings for my friend's wife and he's becoming a monster.
It's not good to have feelings for your friends wife. What is making him into a monster?
I've been checking out her profile and she has a nice and sexy body and I'm not able to stop thinking about her. he's becoming a monster because he is getting in the way of me to her.
You can be attracted to whomever you want, but your feelings and lust are overriding your rationality. He is not a monster, you are the monster for wanting to take his wife away from him. You need to stop being friends before you do something bad to ruin your relationship.
I no longer have interest in him, he's not my friend anymore, he is the one who is not letting us hangout.
Your friend isn't a monster for wanting to preserve his marriage and keep you from getting closer to his wife. If you were a real friend then you would understand his feelings instead of demonizing him over them. It sounds like you no longer want to be friends with him so at least be honest and tell him why.
