I am really not feeling well

This might sound super stupid but i am living it and i need to vent. I am 3 months pregnant and my man is just amazing, after a failed marriage i found the man of my dreams. Lately I've been feeling more insecure than ever, i am a thick women 12-14 jeans size big butt hips and boobs and my boyfriends exes are all skinny skinny. Lately this is killing me i am always questioning why me why he picked me why if i dont look nothing like his "type" never felt like this before i feel ugly not attractive fat my belly is of course growing.. i just needed yo vent and please dont judge me i am really struggling with myself lately
