Dude. Pump the breaks. Start over.
She's feeling like you're just with her because you don't know any better. The relationship is blah. Get a babysitter. Take her out somewhere fancy. Go dancing. Do something romantic. Ignite the spark again. Make her feel like her prebaby self.

Went through the same thing but I was married and had a house and 3 kids with her, after about 7 years she started cheating on me secretly by going out with her friends and then staying out all hours of the night. Still dealt with this for more years for kids sake but finally getting divorced. You still have a chance if you go to couples counseling and try to do more things together , maybe tell her how nice she looks at times but be subtle so it doesn't seem fake
