I am dying.......... 😔😔😭😭😭😭😭

So my husband is on 12 hour shifts. So sometimes I understand when he’s to tired for sex. But I have wanted sex almost every night for a week...... I get nothing, I put on a thong and walked into our room tonight, and he kinda smirked like he didn’t want any. I asked if he was tired, he said yeah and his head really hurt. Fine way to make me feel like shit. And I go change and haven’t talked to him. But this morning he wanted sex so bad while our kids were in the room.... that is my 1 rule no sex while our kids are in the room. I am starting to feel like I am not good enough anymore. Last time we had sex I didn’t even know he had came, it was just like he was in me and then he was done.
