Am I overreacting?! Be honest.

okay so this past Saturday was my birthday and my boyfriend thought it was on Sunday which bugged me a bit but too much. Anyways before that he’s been super dry and seeming like he was loosing interest in me. I text him the day after my birthday telling him we need to talk because things don’t feel right. So he calls and tells me that he’s sorry for lagging and that he just needed time for himself??? but at the same time he’s laughing?? I got pretty annoyed at this and he kept saying I was over reacting. Anyways ever since that call we haven’t talked because I’m giving him “time for himself”. I really don’t know what to do. I feel like I’m a burden to him/ wasting my time. I truly love him and I seem to not be able to let go. I don’t think I was overreacting but according to him I was/am /:
