How to tell him

Per a hpt I'm prego. I'm excited but afraid to tell my hubby as I fear he won't be. We haven't been on the greatest terms lately. We decided to start to try for #2 around Xmas... But he's been back and forth ever since.... Lately he's been so moody (do males get pms? Lol) I'm afraid he won't be welcoming to a child now and just not sure how he'll react.... Everyone hoped for their SO to be as excited as them but I fear he won't be..... Advice/support welcome please!
