Need advice on giving space

So this is a long story and I’ll try to cut it down as much as possible. My boyfriend and I have been together for half a year and it’s been great! I’ve realized though that I’m not the best at giving him me time, he needs more space than I do so sometimes I really just don’t realize when he needs it. I’m trying to be more mindful of that and we’ve had conversations about it, the last week we had some issues, we’re alright now but he’s been in very toxic relationships and feels as if he can’t tell me when something is wrong sometimes, he told me that he had contemplated breaking up because he didn’t know what to do and he didn’t know how to tell me how he was feeling. He told me that when he saw me on Sunday morning he realized that wasn’t the right decision to make, I told him I’m going to be making a lot of changes I just need him to be patient with me because I can’t do it all in one day. He said okay and I’m doing my best to set days for us both to have time to ourselves so I don’t make him feel suffocated. I’ve been through a lot in life and sometimes hold onto good things too tightly bc I haven’t had them much and don’t feel worthy of them a lot. I was just looking for advice on how to give him more space without overthinking too much or getting in my own head. If anyone has any advice on how to make this easier on me so I can respect his boundaries and personal space I would love that, I truly am trying to change things it’s just difficult.
