Should I leave him

My boyfriend and I been together for 6 years and have a 3 year old together. We use to get into plenty of fights but for the past two years we seem to have gotten better for the most part. We still have little disagreements here and there but nothing like how it use to be. But randomly I just feel like I’m not into him anymore .. it seems like he just has a negative aura that I don’t want to be around. We live together and in the mornings I leave the bed before he gets up so I don’t have to talk to him right away and I just try not to talk to him as much as possible. I’m not sure where this is really even coming from.
