Am I really what he wants?

Hey guys so my boyfriend and I just had a beautiful baby boy 5 weeks ago, and he says nothings changed but I feel like it has. He follows a lot of different porn accounts on Snapchat and they are all the exact opposite of me. They have long blonde hair, big boobs, great asses, a thigh gap, and are super fit. I put on 50 pounds through the pregnancy as well as ending up severely depressed. I feel like I'm going to lose him because I'm not what he wants. What do I do? (Pic of me before and after

for reference please be nice I'm self conscious on my own)
