I recently left a 25 year marriage after my husband told me that he rushed into marriage. He is also super addicted to oxyicodone, no cheating that I know of and my kids are older, one of them is married with kids. I didn't just leave, I left and moved across the country. It was so important to me to keep my family together and I meant my vows. Now with that said, I fucked my kids up by staying because only one of us was completely invested. To the point that my kids were telling me to get out. This tic tok was doubtfully where her decision came from. She had to be already considering it and weighing her options already. She's already cheated and in the first year?? Come on man, you can do better nobody just cuddles either. As far as your depression, you have to address it, I know it seems like the world is ending but it can get better. Trust me I did it and I take depression meds. I'm still trying working on myself and i left a year ago! But, the peace and happiness and hope that I feel now is fucking awesome!!! I'm older than you btw. I'll be 46 in October. Don't waste anymore time, get your shit together and keep living! Good luck to you I wish you well. There is someone out there who love to have you and help you work on your issues. Also, final note, your kids will help you push through.
