Is he interested? Or just playing along

I started dating a guy over a month ago, since we met (at a bar) he has asked me on dates every weekend, I was attracted to him because he seemed so genuine and kind. He always plans what we are going to do and makes a real effort on plans in general.

I told him I liked him on date 6 and he said he likes me too, I have meet a few of his friends and he always introduces me to them happily even proudly,He’s 26 (I’m 24) and never been in a serious relationship, however has told me he’s looking for a relationship so that doesn’t concern me hugely.

Trouble is he’s awful at texting, sometimes he doesn’t reply for 24 hours and I find it rude and confusing, since he’s been so bad I have tried to match his energy and not reply as quickly however I really don’t want to play silly games

There’s seems to be something that’s makes me unsure on how he feels and I’m not sure if it’s because I overanalyse everything ( something I’m trying to stop doing) or if he has mediocre feelings about me.

On our last date he was very distant and ‘off’ at first almost as if he was in a bad mood, he became his normal self after an hour or two. he also said when he was younger he used to be very ‘hot and cold’ saying he would ‘get bored and not want to talk to people’ he said this in reference to friends but I think this could be still relevant when I comes to women

Does it sound like a man who isn’t interested long term?
