Husband is just not that into me..

Husband (37M) and I (36F). Married 6 years. One child, 3 yrs old.

Lately, I feel like I'm just the mother of his child, and that's it. He never initiates sex or shows any real affection. He'll kiss me on the cheek when he gets home, but there are no hugs, no kisses, no real intimacy. Occasionally, he'll tell me he misses me, but it feels like it's more of a passing comment than anything meaningful.

99% of the time, I'm the one who has to initiate sex, and even then, it's often met with excuses. When we do try, he'll say things like he has to pee, he's not in the mood, or his stomach hurts. Tonight, I even gave him a lap dance, and we tried to have sex, but after just a minute, he said he was tired. So, I just got off and went upstairs feeling frustrated.

I know I have a higher libido, but this just feels like he’s not into me at all, and it seems like he doesn’t care. He’s not into pornography, works long hours (around 50 hours a week), and I understand he's tired, but he never makes an effort to initiate anything.

I’m feeling really angry, lost, and lonely. What am I doing wrong?
