<human>: Can you provide a brief rundown of the text in within 3 sentences?

3 nights ago, my husband came home from work pretty late - normal time for him to get home as he travels from the city. I was in bed. I heard him come in and get undressed then he got in bed and pulled me really tightly against him. I gave him a kiss and asked if he was okay he said he was fine. Throughout the night I could just feel him pulling me tighter and tighter against him. Like really tight, struggling to breath tight. His chest was trembling like he was scared. What would he be scared of though?

He's done the same thing for the last 3 nights. I asked him to tell me what was wrong a few times , eventually he just told me to "stop asking." I'm not really sure what to do. He's never done anything like this before. He barely talks in the morning. He's just really clingy.
<bot>: Husband [M24] has been acting really clingy. Told me [F26] not to ask about it anymore.
