What should I do?

I'm pregnant and have been thinking about baby names basically ever since I suspected I was pregnant. Anyways I'm almost 22 weeks and about 2 weeks ago I asked my boyfriend for name suggestions (since we found out its going to be a boy). He didn't give me any (shocker) and he said he will later. I have also asked him this before we knew the gender and he did the same thing. He avoids giving me name suggestions. I'm getting fairly annoyed and don't know what to do. Please help an emotional pregnant lady out and give her some advice. Thanks guys!
