Husband doesnt love me - should I be worried ?

So my husband was emotionally abusive and only showed his affection when I threatened to leave , no he doesn't text me much at all and ignores me. His sister is currently living with him in the US and she's messaging saying he's been on his phone but just hasn't replied to me for some reason

I'm honestly sick and tired of trying to force conversations out of him, I feel so embarrassed and humiliated . I'm just his pregnant needy wife probably in his eyes

Ill end up jumping to conclusions that he's met another girl which is what I thought earlier . his single colleague friend would go to bbqs with us and he was always really pally with her

Do I just give up?

I feel like a pathetic school girl trying to get my crush to like me. He doesn't love me I just know it, the horrible part is..he obviously just doesn't care.

I mean , do I take it personally that someone doesn't love me back despite my efforts ???
