What is going on ?!

Jay
Ive been with my so for 2 years , I gave birth 7 wks ago and for the past few weeks it seems like I'm begging for his affection / attention. We have always had a great relationship, trusting caring and a sex life a good one , but now it seems like he doesn't want me like he used to . I felt it while I was pregnant as well but figured it will pass once I had our son but it seems to only have gotten worse 😞 idk what to do any more, ive told him how I feel but it's still the same. I know he isn't cheating but I also know he isn't emotionally involved as he used to be 😔 what is going on ? What do you ladies think is happening here , did he fall out of love already ?!
