I’m going to be the only one to advise you not to rush into anything as extreme as a divorce before speaking to a professional if they are readily available in your area. I don’t have time to expand on my post here right now and I certainly don’t want to diminish everyone else’s advice but some things in my opinion shouldn’t hinge on the advice of others over the internet. there are many, many facets to your relationship that we all couldn’t possibly know about unless we knew you well and these are the things that a professional therapist could use to piece together a puzzle over time that may help you see things clearer. Or if your mind is 100% made up, they might help you during the divorce process to make things easier. Either way I wish you both the best. Good luck!
