Not in love with my husband anymore

I’m not in love with my husband anymore. We had our baby boy 16 months ago. My husband and I have been on one date since his birth, and he is constantly gone hunting on weekends or off doing something. He goes to bed early on week nights and makes no effort to spend time with me. He currently is next door at a party while I’m at home in case our son wakes up. I honestly feel like a single parent most days and just don’t have any feelings towards him anymore. I feel like we could divorce tomorrow and I wouldn’t care. The only reason I’m still with him is for my son’s sake, which I hate to say.

Anyone else feel this way?
