My FWB has stopped cuddling me

Me and my FWB started sleeping with each other again 9 weeks ago after not seeing each other for 4 years due to a bad parting and me getting in a relationship.
The first 7 weeks were great. Amazing sex and he was always affectionate with me like we’d never been apart.
I always stay the night in his bed. We’d always end up having sex before we fell asleep and he would always touch, kiss and cuddle me in the morning as we woke up.
The last two nights I have a slept there he hasn’t touched me when we’ve been in bed. No spoon during the night, no cuddles in the morning. Nothing! It’s all just stopped and he gets straight out of bed.
The affection has still been great before we get in bed however.
The first time I put it down to him having a bad nights sleep due to a leg injury and the second time he said he felt rough due to having a cold but I’m not convinced. Should I ask him about this as it really bugging me. Something is off.
