Sounds like maybe you guys need to have someone watch your baby for an evening so the two of you can go out and enjoy yourselves.

In any type of relationship you always have to keep things spicy, maybe trying planing a night of romance, in the sense of getting some wine, grapes, cheese and crackers, along with some candle and just have a romantic evening together, just the TWO of you, or you could try Role Playing, maybe you could wear a nice nighty for him, fill the tube up and you both enjoy a bath together, there is a lot of things that you can do,

You need to come closer to him, not the wrong way. Take him to carnivals. Make him happy in anyway you can. Get to know him by asking questions. If you end up hating each other take couples' therapy.

Hope I helped,
