Hormones or ??

So before I got pregnant my boyfriend could NOT stay away from me we practically lived together in the beginning and we talked all day long and he always would compliment my appearance bring me little gifts and would always want me to sit right beside him in the truck and hold my hand and took me out on a date atleast once a week, since finding out I was pregnant he has completely changed, no compliments, no hand holding, only kisses me bye when I do see him which is once a week sometimes even once every two weeks. Sends maybe one or two texts a day, he doesn’t ever touch my belly, or interact with baby in any way, shape or form, he has not taken me on a date in three months and makes me do all the traveling to him which is an hour drive there and often times makes me pay for dinner which is drive-thru or something ordered from waitr. I am six months pregnant and just overall am feeling neglected, and when I bring something up about his behavior he just tries to guilt me and says “what else am I doing wrong? Nothing I am doing can seem to make you happy and I just don’t know what to do anymore.” I love him but I feel so alone and I don’t feel as though my emotional needs are being met.. I also forgot to mention, he never posts pictures of me or our unborn child anywhere, he never likes my pictures but can seem to like other girls half-naked photos..
