Hubby not supportive anymore

I'm 10 weeks 1day today we found out at 3 weeks and at first he was so excited and genuinely happy but the past 2 weeks he keeps saying he not sure he wants to be a dad anymore because I've turned "boring" I take the fun out of everything he usually says this after quite a few drinks but next day he fine until the drinks are flowing "drunken mans words are sober mans thoughts" but I don't feel like I'm boring just cos I'm not drinking with him I'm just being extremely cautious with having 5 previous miscarriages!! When he says all this it makes me doubt a lot of things and it's getting me really down at moment 😢 x
