Give up

My boyfriend is never in the house he’s at work Yh that’s fine but he doesn’t work weekends,, even on weekends he’s gone all day and comes back late at night, I face time him during the day but then he always gets home late, even weekends! He has kids with other women from before I met him, he’s spending all day with one of his kids that’s fine, but I know tonight he’s gonna be out with his friends instead of coming back to me, I’m 12 weeks pregnant and feel like he doesn’t care. I feel like he’s just messing me about
