38 weeks pregnant and feeling unloved and lonely

Maria
My BF is so emotionless, we dont even have a normal conversation. He wont text or call so i dont even have the courage to ask him if he even likes me. He's there for his kids that he has from a previous relationship. He takes them to school, calls and text to see how they are. But he wont do that to me. Im 38 weeks pregnant and he never hugs, kisses, holds my hand, or even tell me he loves me... yesterday i had an appointment and he decided to take me, well i thought he was going to go in with me. I was happy because he has never gone with me not even to the ultrasound appointment, well nope he waited in the car.. i feel so alone and i just want to ask him and know because i dont want to be stuck this way especially with a baby here... i love him but im not going to force him into anything... im not going to hold or even beg him, if he wants to leave he can even if it hurts but im always depressed... i feel unloved and if he wants quit well it better be before the baby is here.Cause this baby wont have his last name if he's not going to be here for us physically and emotionally. He can see me crying and he wont say a thing. I just dont know what to day anymore...
