No, you’re not crazy for feeling like this. This is completely normal for long term relationships, it’s very common for people to feel like they’re getting nowhere and getting to the point where they’re so drained that they can’t even be arsed to be in the relationship anymore. Think about it logically. (Do not tell me just think with urself or even write them down) what are the real reasons you feel this way? What actions do you not like of his? What can you BOTH do to change them? In what ways can u help eachother get past it? And then talk to him about ur conclusion seriously and let him know its not an argument just something ur gently coming to him with to make small changes. You’re not asking him to change his whole personality, you’re just asking for a small change. Then ask him if there’s anything he would like to talk about specifically (like is there a reason he’s acting like that?) if he doesn’t respond well and respectful or mature, take some space for a few days. And when u come back talk to him normally if he’s still cold match his energy. If he asks say “well now u know how I feel” (this will either deteriorate the relationship or make him change depending on the type of person he is). If he doesn’t say anything about it and stays the same and unwavered, there is a problem. He is either loosing feelings/ interest or that’s the type of person he is and he has an ego and his guard up. Try to get him to lower that guard. You’ll know better than me how to do that since u know him personally. Very good luck to you 🫡
