marriage rough patch... 😞

No judgement please! I just need somewhere to talk this out because I can't say it out loud to anyone else. My husband and I are basically roommates. I would never leave because I could never do that to my daughter or either of our families. We barely talk because we barely see each other between our crazy schedules. And here's the worst part....
I've started to develop a friendship with a man I work with.  I NEVER imagined I would be that woman. Ever. I'm so disgusted with myself but I can't seem to stop looking forward to work so I can see and talk to him. I feel like the worst kind of person. I know it's just because I'm not getting attention in my marriage and he is a nice guy who is there to talk. 
I guess I just want to hear that someone went through this same thing and came out with a stronger marriage in the end. I know I need to be putting all my attention and emotions into working on my marriage but I'm finding it so difficult. 
Reading back through this I can't even believe the words I wrote. Ugh. Any advice or similar experiences?
