Why would he say he misses me too but show less affection in his text?

He messages me first to ensure we don’t lose touch, we’re not in love yet but we are exclusive. I’ve just been seeing how things go. I found myself missing him after some time apart. He’s the one that initiated meeting up again and arranged it but when I said I’m looking forward to it as I’ve missed him he responded by saying he missed me too but put less kisses in his message (which I’m sure was deliberate because he does tend to use affection like that to let me know when he is or isn’t happy). I can’t ask him because I’m just not convinced id get the truth tbh.
