Am I overreacting or does my SO seriously think only of himself? (A little long sorry) but plz help

So anytime I am doing something or buying something I always think of my SO and get something for him as well if I get something for myself or I find myself calling and asking him what would he like or what does he need. Just yesterday I bought my SO a new phone. Next day we are texting and going about our days and he doesn't bother to tell me what he's doing but is constantly asking me over and over then when I see him he has just got new clothes and new hair cut and other items he purchased as well but all for himself. Is it wrong of me to feel some type of way that he didn't even care to ask me nor think of me to do anything for me or bother telling me what he was up to today? But yet hounds me and I include him literally EVERY time. Or is it I just do too much for him than he does back. Please honest replies, they will help me figure this out greatly no matter what it is said. Much appreciated.
