Should I go blonde for a guy??

I love coloring my hair and for the last 5 months i’ve been a very dark brown, practically black color. before i had this color, i was red and before that, i was blonde for 3 years. this guy that i’ve been talking to said he really wants me to go blonde..... should i go back?

this is me now:

and this is me blonde (it was the first pic i had, roots are well in LMAO I KNOW):

i don’t know, i just don’t know if i do this, if it’s for me or for him.
