so basically I need help with writing this before I tell him, but would like some help with wording. This is what I have so far:

I need you to sit down and just listen, don't talk dont argue, just listen.

I know that you've noticed I have been differnt lately, though for some reason, and I dont particularly care what that reason may be, but you have't asked me directly. Ive been distant and havent discussed it you, because it would change everything. Remember one saturday you asked me what was up and I said something along the lines of obliterating our relationship, I lied when I told you whatever I told you. Truth is everything is different and I dont know how to really approuch this. I love you dearly, but I dont think of you the same way I used to, I dont look at you the same, I dont feel the same about you and its tearing me up inside. How can I stay with a man that I dont feel anything for? Dont get me wrong i still love you, and allways will, but I dont think we can work out this problem, I dont think we can just fix this. I can give you theories on why I feel this way, but In all honesty I think the whys dont matter. Isaac, Ive been think a lot on this, exspecially the last few weeks, and have come to the conclusion that I have to break up with you, dont argie with it, dont try to get me back, dont try anything. The most I ask of you is to support my Decision. I know it will take a while to get over it, and I know this is coming as a shovk to  and I hope you can accept it. Ive held it in for a while now trying to figure things out, and im pretty certain that this is the next step in my life.

Firstly, no need to try and interpret my situation or tell me what I should or shouldn't do. Secondly noticr I didnt ask for advice besides the wording.
