Is it normal for my boyfriend to not know what to feel?

Hello everyone ! I've been with my boyfriend for already 7 months before him I had a 5 year relationship that was terrible but once I met my current bf now he has helped me move on build trust and smile again ! I'm his first serious & long relationship & we are very alike so you wouldn't think we would argue a lot. For the first couple of months it was perfect he would put his 100 into it and would want to see me all the time and spend every momment free he could with me. We're 7 months into the relationship and the last 2 months has only been fights.. He's been acting different hasn't been asking to see me as much , started telling me he wants to be with me but at the same time he doesn't, qhe started wanting to be alone a lot , he's long texts turned into barely anything, has been acting careless so this month he told me he needs time for himself and figure out what he wants because he doesn't know if he wants to be with me anymore due to all of the arguing. He had the couple days to himself and came back to me telling me he doesn't want to loose me and will try to change and be the man I met. It's been a week since he told me he'll change and he told me even tough we stopped fighting and are doing better he still feels like he did before. Can anyone please tell me what it is? Am I too clingy and not giving him space to miss me or is there no help to this? I love this guy and don't want to loose him can someone tell me what I'm doing wrong ?
