How do I tell him?

CC
My hubby and I haven't been on the greatest terms lately and weren't trying persay.... But we weren't preventing anything for several months either (around Xmas decided to try again and he's been back and forth about it since then....) . Now I'm pregnant per a hpt and I don't know how to tell him cause I'm afraid he won't be excited.... Wasn't expecting this and while I am excited I fear he won't be because of how things have been lately between us. Advice and/or support would be greatly appreciated.
