I feel like my husband doesn’t love me anymore like he once did

Before we had our son, my husband was very affectionate towards me. He always wanted to cuddle & would always kiss me without me having to ASK. I know intimacy isn’t the same when you have kids but i literally have to ASK my husband to hug me or kiss me. My son is 2 years old. When we argue he’s so cold and will ignore me for days at a time. When I tell him that I want to be hugged or cuddled he always rolls his eyes and it feels like I’m forcing him to do it. I don’t even feel like he’s doing it cause he wants to. I’m crying so bad right now because I was literally trying to just TOUCH him because I’ve missed him (he’s been working nights so he’s been sleeping all day until he has to leave) and he tells me he didn’t want me touching him because it was “too hot” even though we had the AC on!!! Idk if I’m just overthinking but I just really miss how he used to be. I feel like I’m literally always looking for him to get attention and I’m getting so fucking depressed because he shows so much love and affection to our son (as he should) but I feel like he needs to do the same to his wife…😞
