I think writing this down is going to make me sound very silly and naive but I’m just so confused about my exP’s behaviour
We didn’t have a long relationship (6 months) due to circumstances at the time which are now resolved. We’ve always been in touch since we split and a couple months ago he wanted us to try again. He tried for weeks to get me to give it a go.
I was hesitant as I’d just started feeling better about being single so he gave up but said his offer still stood if I changed my mind
We slept together a few times in between (my initiation) usually when I’d had a few drinks 
We met up again a few nights ago and had a lovely evening together, slept together.
He said a lot of things that night that implied he wanted to be with me and missed me. He was very affectionate and we acted how we used to.
He also said I always seem to go quiet after we’ve had sex so he doesn’t know what to think so I’ve made more effort to be in contact. He always responds but it’s often quite short and no real conversation.
I’ve asked him when we can meet up and go out together and he’s told me he doesn’t know, he’s very busy at the moment!!!
I’m so confused at the mixed signals. Why say all those things??
I don’t think he says what he says to get me into bed, he always says these things after we’ve dtd and he always seems genuine!
I’ve just read this back and it sounds ridiculous 
Is this me being a massive mug and he really doesn’t want me at all? Is it some kind of game playing because I rejected his offer before?
I actually still really like him and I would love to give things another go so want to try and understand what exactly is going on
