i’m pregnant and my fiance wants to leave me

basically the title. i’m (F) 14w and i feel my fiance (M) slipping away. i don’t really know what to do. during my first trimester we had a big argument and he told me that we were over and that he was leaving. we ended up working things out but ever since i feel like hes just playing nice because we’re having a child. as much as i love him and WANT him to be with me, i dont understand what ive done to make him feel like he needs to fake a relationship with me to have access to his child. it hurts because im so deeply in love with him, and envisioned us making it to our wedding day and nurturing our little soon-to-be family.

when we first got together he was completely obsessed with me. wouldn’t leave my side and was always wanting my attention. that was new for me so of course at first i had no idea how to handle it, and that lasted just until recently. now that i think about it, it stopped right around when i found out i was pregnant. he wants this child, actually, he’s OBSESSED with this child, so i don’t believe that’s the issue. i knew that us bringing this lovely baby into the world was going to change our relationship dynamic, but i didn’t realize it would be this much. we wake up, go to work, i wait all day to text him on his 30 min lunch because he can’t have his phone in the building and he takes forever to respond and never says anything deeper than the weather, we go home and he talks on the phone with his friends or is constantly watching videos, i feel so lonely. i miss him. i miss our quality time. he’s cold to me and gets irritated when i ask him to help me out or do things for me that he used to just do on his own. i used to be the queen of his world. even our intimate time feels like no effort is being put in, i wanna be cherished and not just there for a transaction. it’s also hard because my body is changing so much already and my self esteem is at the lowest it’s ever been and he never compliments me anymore, and if i ask if i look good that day he tells me to stop fishing.

i get that my hormones are everywhere right now and might have a role to play in all this, but im so truly upset. ive mentioned therapy and he always agrees but later will act like he doesn’t have the time of day. we do argue more often than not, mostly about the way i’m treated and his money habits, and i understand that im probably a lot to deal with between pregnancy and my high standards i hold for him. but he made me this way. he made me expect so much. i just don’t know how to fix this. i feel like people always end up falling out of love with me, but i didn’t think he ever would, too. any advice?
