Cheating husband again

I am so tired. So tired. I don’t want marriage again. I hate marriage. I am done. Constantly being cheated on by a man you’ve loved for 10 years and given 3 children. What do men really want? This man has driven me to depression. I eat to compress my pain. I forgave his previous cheating because I honestly don’t have anywhere to go if I leave or any money. I don’t have a job, I just completed my degree so I haven’t gained an employment yet. But I can’t stay anymore. My children need me. This man moved relocated us out of the country 4 years ago so I don’t have family here… I was not allowed to work… he wanted a stay at home wife. Took a lot of convincing to get him to agree to me finishing my studies. I am always at home, no social life, no friends. He and our children became my family and only friends all in one. I caught him again tonight, he denied it as usual but the evidence is always there. He left for work and I have composed this message to send to him. What do you think? Does it sound rude? I feel like he would deny this happening in the future and make me look like the bad person so I think also putting this down as a message would be one of my evidence. I don’t know where I will go from here but even sleeping on the streets is better than crying myself to sleep every night.
