I've fallen in love with a coworker and I can't leave my wife because she's entirely dependent on my support(she doesn't work or drive) and I will almost assuredly lose my son if I do leave. My mom also lives with us and I'm the only real breadwinner and physically capable person in the household. So if I leave I have essentially screwed over 3 adults and will screw up my son who's 8. I seperated from my wife for a week and was going to teach her how to drive, and help her get situated with a job so she could be self sufficient while I slept on the couch,but all that ended up with me being brow beaten by my mom and my wife doing her best to guild trip me into not and then both making it clear if I left I would be miserable and I wouldn't get my son. So now I'm back with my wife pretending like I love her. I'm going to the doctors soon to see about being out on antidepressants because I stopped taking medications for it years ago and it was fine but over the past year or so it's gotten worse. This is not all of it and I'm in no way a saint but in the grand scheme of things I just needed somewhere to write all this out and say it and what better place than a place full of strangers.
Edit: for the record the coworker wasn't the catalyst in feeling this way towards my wife, we had already been having problems for years at this point and I had been contemplating leaving her for over a year just so it isn't misconstrued as me only wanting this because of the coworker.
