Please don't judge me

Ok please don't judge me so I have a boyfriend and I have a best friend male but since I had my son last year my bestfriend have been by my side he helps me with my son he play with my son yesterday it was me my son and my best friend so my son and my best friend was playing while we was out and my son called him daddy I didn't say nothing cause my son is only 1 so he doesn't know no better but my best friend has feelings for me and I kinda have feelings for him and to be honest he treat me better than my boyfriend he gives me attention and tells me that I am beautiful and he gives me advice on different situations so my question is what should I do should I just remain best friends or tell him how I feel about him and please don't judge me
