Second thoughts?

So when my partner broke up with me about 6 weeks ago I was heartbroken. I just wanted him back and probably came off as desperate to him because I was always so sad. Our relationship was turbulent at times, I believed it was fixable but he didn't. We still live together which I know isn't ideal but I'm in the process of finding something. I'd rather be the one to leave to start fresh in a new place. Too many memories in our house. So anyway.... When we first split there wasn't much conversation at all, we'd try and avoid each other but as the weeks have gone on we actually now sit in each others company and even have a few drinks together. And he says some things like, for example: he installed a new light in the back yard a few days ago and said he'll probably install another one right at the top of the garden for 'the future for next summer when we want to sit up there at night'. He's said he'll always love me and he already knows how I feel so I don't need to put myself on a plate any more than I stupidly have. We have been laughing, joking and getting on so well. But I've also been having serious conversations with him about the obvious situation we're in. I've mentioned to him that I've possible found a house, it's not too far away, it's a step in the right direction though for me. He just goes quiet and doesn't really engage in the conversation, this is what he wanted though! He wanted to end it so its inevitable that one day one of us is gonna move out. Also I've stopped trying to get back together with him, I'd love to don't get me wrong, but I've realised begging and chasing isn't an attractive look so I've been doing me and looking after me and our kids. Our house lately is full of fun and laughter for all of us. He said last night he'd miss us all when we leave and that he loves our 'madhouse' does this sound like he's having second thoughts do you think? Also he ordered me my Christmas present last night, why would he still wanna buy me stuff. Its so confusing, I don't wanna ask him about his feelings because like I said, I don't wanna ruin whats happening right now if I'm wrong
