Honestly any person who's been in a relationship past a couple years will tell you these ruts happen and they're perfectly normal. This is the harsh reality of love.

Love isn't like romantic comedies, where you're swept off your feet by some smoking hot pixie spirited introvert who's just like you. No, love is waking up in the hospital to your wife by your side and knowing that you wouldn't be alive if she wasn't in your life.

The sad reality is the passion smolders, the sex subsides, but you gain a true partner and best friend. The first person who will be there when God forbid, something terrible happens, on the flipside, the first person you will want to share something amazing with.

The sadder reality is like everything in life your relationship is a total reflection of you as a person and you get back what you give into it. At this point you've grown so comfortable and bored, and there's probably some hotter chick at work who's flirting with you cuz they know you're taken and that's just human nature. However, if you want to have a passionate relationship you have to start trying harder, make changes that will lead you guys to what you want. Nothing happens in the blink of an eye. If you want her to be hotter you have to change your diet and start exercising and the results will be slow until one day you'll see her in underwear and be like !!

Also, have you considered seeing a therapist? It sounds like you could be depressed and benefit from talking to someone. Just a suggestion, take it as you will.

Lastly, really realize what life would be like w/o her or with someone else and how worse or better things could be. Truly consider what it will feel like when you're single again? Will you partying and slaying ass really? Will that make you happy? For how long? What's the odds of meeting someone else who will put up with you shit and whose shit you can put up with? These are all important questions for you to ask yourself before reaching a decision. Whatever you choose... Good luck
