Pregnant with an unsympathetic husband

Hello lovely ladies and maybe lovely husbands too.

I'm having a hard time wondering why I'm with my husband, who I've been married to for 3 years and with for 5. We have a 19m old son, and I'm 12 weeks pregnant. Intimacy isn't there, and fortunately we were able to conceive quickly, so it was basically a quick round of sex each time to try for a baby. I recently showed him baby's size etc (according to this app), and his answer was 'I'm so uninterested by this pregnancy.' He's not passionate, has no consideration about turning me on, nor does he give a shit when I'm feeling rough or tired because of this pregnancy, and life with a toddler. I look at him and hate his face. I sometimes wish I could just walk out, but I'm in too deep. We live in a different country from our respective homes. We're not from the same country either.

He does well work wise, and is the 'sensible' man I wanted, but with a lack of emotion or interest in me (he doesn't know me at all), I'm feeling so lost. Going to sleep is an escape from him, as is him going to work. Fed up of moaning about him. I just don't know what to do. I booked a date night for us both the other night as we've really struggled recently, he spent most the time on his phone messaging his family who also lack emotion, and checking golf scores.

I don't know what to do to make it better. Any ideas would be so appreciated. Thank you.
