Is he falling for me again ?

So me and my child’s father have moved back in together we have a 2 month old now and we are not together but have a very very strong bond we are still sleeping together and now he seems a lot more caring even though we both tell each other we do not want a relationship 😒❤️ however it’s just weird because I feel like he low key wants me again but has a guard up and won’t tell me
