I wasn't either... I literally had to cry and tell him how much I need his support and that if he can't support me now then I won't be around to watch him not support me and our kid later. It's not the best way to do it but it got my guys attention.
My boyfriend was really unsupportive at first. He wouldnt even let me talk about the baby with him. he would tell any of his friends.
I am now 20 weeks. He was like this untill i took him with me to the u/s and to find out the sex. now he wont shut up about when the baby is born and baby names. he even went with me to look at cribs by his suggestion.
I know its hard trust me, i was struggling bad when he was ignoring me and the situation but i just gave it time and now hes excited as i am.
